    The complexity of subdifferentiation and its inverse on convex functions in Banach spaces.Pierre Casevitz - 2002 - Annals of Pure and Applied Logic 118 (3):197-217.
    Let E be a separable Banach space with separable dual. We show that the operation of subdifferentiation and the inverse operation are Borel from the convex functions on E into the monotone operators on E for the Effros–Borel structures.We also prove that the set of derivatives of differentiable convex functions is coanalytic non-Borel, by using the already known fact that the set of differentiable convex functions is itself coanalytic non-Borel, as proved in Bossard et al. 142).At last, we give (...)

    Complexity of distances: Theory of generalized analytic equivalence relations.Marek Cúth, Michal Doucha & Ondřej Kurka - 2022 - Journal of Mathematical Logic 23 (1).
    We generalize the notion of analytic/Borel equivalence relations, orbit equivalence relations, and Borel reductions between them to their continuous and quantitative counterparts: analytic/Borel pseudometrics, orbit pseudometrics, and Borel reductions between them. We motivate these concepts on examples and we set some basic general theory. We illustrate the new notion of reduction by showing that the Gromov–Hausdorff distance maintains the same complexity if it is defined on the class of all Polish metric spaces, spaces bounded from below, from above, (...)

    Towards a Newer Analytical Frame for Theorizing Ethnic Enclaves in Urban Residential Spaces: A Critical Dialectic Approach in Relational-Spatiality.Nawal Shaharyar - 2023 - Environment, Space, Place 15 (1):116-138.
    This paper provides a critical reflection on the nature of ethnic enclaves and segregation by presenting an analytical frame that can be used to capture the contested nature of spatiality in these spaces. By underscoring the dynamics in which differences constitute distinct subject positions, this paper posits a relational orientation to studying spatiality that is based on complex relations among and between subjects and space. To date, few attempts have been made to present an analytical frame for the (...)

    The Complex Neural Network Model for Mass Appraisal and Scenario Forecasting of the Urban Real Estate Market Value That Adapts Itself to Space and Time.Leonid N. Yasnitsky, Vitaly L. Yasnitsky & Aleksander O. Alekseev - 2021 - Complexity 2021:1-17.
    In the modern scientific literature, there are many reports about the successful application of neural network technologies for solving complex applied problems, in particular, for modeling the urban real estate market. There are neural network models that can perform mass assessment of real estate objects taking into account their construction and operational characteristics. However, these models are static because they do not take into account the changing economic situation over time. Therefore, they quickly become outdated and need frequent updates. (...)

  8. Modeling Semantic Emotion Space Using a 3D Hypercube-Projection: An Innovative Analytical Approach for the Psychology of Emotions.Radek Trnka, Alek Lačev, Karel Balcar, Martin Kuška & Peter Tavel - 2016 - Frontiers in Psychology 7.
    The widely accepted two-dimensional circumplex model of emotions posits that most instances of human emotional experience can be understood within the two general dimensions of valence and activation. Currently, this model is facing some criticism, because complex emotions in particular are hard to define within only these two general dimensions. The present theory-driven study introduces an innovative analytical approach working in a way other than the conventional, two-dimensional paradigm. The main goal was to map and project semantic emotion (...) in terms of mutual positions of various emotion prototypical categories. Participants (N = 187; 54.5% females) judged 16 discrete emotions in terms of valence, intensity, controllability and utility. The results revealed that these four dimensional input measures were uncorrelated. This implies that valence, intensity, controllability and utility represented clearly different qualities of discrete emotions in the judgments of the participants. Based on this data, we constructed a 3D hypercube-projection and compared it with various two-dimensional projections. This contrasting enabled us to detect several sources of bias when working with the traditional, two-dimensional analytical approach. Contrasting two-dimensional and three-dimensional projections revealed that the 2D models provided biased insights about how emotions are conceptually related to one another along multiple dimensions. The results of the present study point out the reductionist nature of the two-dimensional paradigm in the psychological theory of emotions and challenge the widely accepted circumplex model. (shrink)

    The topological complexity of a natural class of norms on Banach spaces.Gilles Godefroy, Mohammed Yahdi & Robert Kaufman - 2001 - Annals of Pure and Applied Logic 111 (1-2):3-13.
    Let X be a non-reflexive Banach space such that X ∗ is separable. Let N be the set of all equivalent norms on X , equipped with the topology of uniform convergence on bounded subsets of X . We show that the subset Z of N consisting of Fréchet-differentiable norms whose dual norm is not strictly convex reduces any difference of analytic sets. It follows that Z is exactly a difference of analytic sets when N is equipped (...)

    Bohmian Trajectories for Kerr–Newman Particles in Complex Space-Time.Mark Davidson - 2018 - Foundations of Physics 48 (11):1590-1616.
    Complexified Liénard–Wiechert potentials simplify the mathematics of Kerr–Newman particles. Here we constrain them by fiat to move along Bohmian trajectories to see if anything interesting occurs, as their equations of motion are not known. A covariant theory due to Stueckelberg is used. This paper deviates from the traditional Bohmian interpretation of quantum mechanics since the electromagnetic interactions of Kerr–Newman particles are dictated by general relativity. A Gaussian wave function is used to produce the Bohmian trajectories, which are found to be (...)

    Morley Degree in Unidimensional Compact Complex Spaces.Dale Radin - 2006 - Journal of Symbolic Logic 71 (2):569 - 585.
    Let A be the category of all reduced compact complex spaces, viewed as a multi-sorted first order structure, in the standard way. Let U be a sub-category of A, which is closed under the taking of products and analytic subsets, and whose morphisms include the projections. Under the assumption that Th(U) is unidimensional, we show that Morley rank is equal to Noetherian dimension, in any elementary extension of U. As a result, we are able to show that Morley (...)

    An Analytic Zariski Structure Over a Field.Nick Peatfield - 2006 - Archive for Mathematical Logic 45 (6):739-768.
    Following the introduction and preliminary investigations of analytic Zariski structures in Peatfield and Zilber (Ann pure Appl Logic 132:125–180, 2005) an example of an analytic Zariski structure extending an algebraically closed field is provided. The example is constructed using Hrushovski’s method of free amalgamation, and a topology is introduced in which we can verify the analytic Zariski axioms.

    Complexity and Social Movement(s).G. Chesters - 2005 - Theory, Culture and Society 22 (5):187-211.
    The rise of networked social movements contesting neo-liberal globalization and protesting the summits of global finance and governance organizations has posed an analytical challenge to social movement theorists and called into question the applicability to this global milieu of the familiar concepts and heuristics utilized in social movement studies. In this article, we argue that the self-defining alter-globalization movement(s) might instead be engaged with as an expression and effect of global complexity, and we draw upon a ‘minor’ literature in social (...)

    Russell’s doctrine of space and time in connection with Kant’s transcendental aesthetics.Viktor Kozlovskyi - 2024 - Sententiae 43 (2):6-32.
    Author demonstrates that Russell’s conception of space and time diverges from Kant’s transcendental aesthetics and leans towards logical and mathematical topology. Russell’s approach is grounded in analytical rather than synthetic judgments, contrasting with Kant’s perspective. The British philosopher develops a subjective-psychological model of space and time that complements the logical-mathematical model, serving as the foundation for human experience and cognition. This Russellian model considers the psychological aspects of perceptual and tactile space and time, highlighting their intersection in (...)

    Complexes, rule-following, and language games: Wittgenstein’s philosophical method and its relevance to semiotics.Sergio Torres-Martínez - 2021 - Semiotica 2021 (242):63-100.
    This paper forges links between early analytic philosophy and the posits of semiotics. I show that there are some striking and potentially quite important, but perhaps unrecognized, connections between three key concepts in Wittgenstein’s middle and later philosophy, namely, complex, rule-following, and language games. This reveals the existence of a conceptual continuity between Wittgenstein’s “early” and “later” philosophy that can be applied to the analysis of the iterability of representation in computer-generated images. Methodologically, this paper clarifies to at (...)

Seen from a broad perspective, a potentially productive means of understanding the complexities of this sphere is through the lens of Michel Foucault’s notion of governmentality—a concept that ties together the actions and preferred outcomes (...)

    How Complex, Probable, and Predictable is Genetically Driven Red Queen Chaos?Jorge Duarte, Carla Rodrigues, Cristina Januário, Nuno Martins & Josep Sardanyés - 2015 - Acta Biotheoretica 63 (4):341-361.
    Coevolution between two antagonistic species has been widely studied theoretically for both ecologically- and genetically-driven Red Queen dynamics. A typical outcome of these systems is an oscillatory behavior causing an endless series of one species adaptation and others counter-adaptation. More recently, a mathematical model combining a three-species food chain system with an adaptive dynamics approach revealed genetically driven chaotic Red Queen coevolution. In the present article, we analyze this mathematical model mainly focusing on the impact of species rates of evolution (...)

    A complex formulation of generalized Hamiltonian (Birkhoffian) theory.J. McEwan - 1993 - Foundations of Physics 23 (2):313-327.
    Fundamental analytic, algebraic, and geometric properties of generalized Hamiltonian (Birkhoffian) theory are compared with the properties of a covering unitary phase-space formulation based on complex variables of the form (p+iq). Technical advantages in the unitary phase-space formulation are illustrated by a detailed discussion of the one-dimensional extended damped harmonic oscillator. One advantage is the ability to fully describe nonconservative constraint forces within a globally conservative system. Another advantage is that wider classes of gauge transformations are available (...)

    Analytical Comparison of Two Emotion Classification Models Based on Convolutional Neural Networks.Huiping Jiang, Demeng Wu, Rui Jiao & Zongnan Wang - 2021 - Complexity 2021:1-9.
    Electroencephalography is the measurement of neuronal activity in different areas of the brain through the use of electrodes. As EEG signal technology has matured over the years, it has been applied in various methods to EEG emotion recognition, most significantly including the use of convolutional neural network. However, these methods are still not ideal, and shortcomings have been found in the results of some models of EEG feature extraction and classification. In this study, two CNN models were selected for the (...)

    The descriptive set-theoretical complexity of the embeddability relation on models of large size.Luca Motto Ros - 2013 - Annals of Pure and Applied Logic 164 (12):1454-1492.
    We show that if κ is a weakly compact cardinal then the embeddability relation on trees of size κ is invariantly universal. This means that for every analytic quasi-order R on the generalized Cantor space View the MathML source there is an Lκ+κ-sentence φ such that the embeddability relation on its models of size κ, which are all trees, is Borel bi-reducible to R. In particular, this implies that the relation of embeddability on trees of size κ is (...)

    The Equiareal Archimedean Synchronization Method of the Quantum Symplectic Phase Space: II. Circle-Valued Moment Map, Integrality, and Symplectic Abelian Shadows.Elias Zafiris - 2022 - Foundations of Physics 52 (2):1-32.
    The quantum transition probability assignment is an equiareal transformation from the annulus of symplectic spinorial amplitudes to the disk of complex state vectors, which makes it equivalent to the equiareal projection of Archimedes. The latter corresponds to a symplectic synchronization method, which applies to the quantum phase space in view of Weyl’s quantization approach involving an Abelian group of unitary ray rotations. We show that Archimedes’ method of synchronization, in terms of a measure-preserving transformation to an equiareal disk, (...)

    Covers of Abelian varieties as analytic Zariski structures.Misha Gavrilovich - 2012 - Annals of Pure and Applied Logic 163 (11):1524-1548.
    We use tools of mathematical logic to analyse the notion of a path on a complex algebraic variety, and are led to formulate a “rigidity” property of fundamental groups specific to algebraic varieties, as well as to define a bona fide topology closely related to etale topology. These appear as criteria for ℵ1-categoricity, or rather stability and homogeneity, of the formal countable language we propose to describe homotopy classes of paths on a variety, or equivalently, its universal covering (...).Technically, for a variety A defined over a finite field extension of the field Q of rational numbers, we introduce a countable language L describing the universal covering space of A, or, equivalently, homotopy classes of paths in A. Under some assumptions on A source we show that the universal covering space of A is an analytic Zariski structure [26]), and present an Lω1ω)-sentence axiomatising the class containing the structure and that is stable and homogeneous over elementary submodels. The “rigidity” condition on fundamental groups says that projection of the fundamental group of a variety is the fundamental group of the projection, up to finite index and under some irreducibility assumptions, and is used to prove that the projection of an irreducible closed set is closed in the analytic Zariski structure.In particular, we define an analytic Zariski structure on the universal covering space of an Abelian variety defined over a finite extension of the field Q of rational numbers.

    ABSTRACT: In this chapter I argue that Sellars’s philosophy was deeply pragmatist both in its motivation and in its content, whether considered conceptually, historically, or in his own estimation, and that this is the case even in the important respects in which his views differ from most pragmatists. However, this assessment has been rejected by many recent pragmatists, with “classicalist” pragmatists frequently objecting to Sellars’s analytic-pragmatist privileging of language at the alleged expense of experience, while many analytic pragmatists (...)

    Creative Listening and the Psychoanalytic Process: Sensibility, Engagement and Envisioning.Fred L. Griffin - 2016 - Routledge.
    Contemporary psychoanalytic thinking about the interdependence of subjectivity and intersubjectivity has reenvisioned the analytic process, and with it the very nature of creative and engaged psychoanalytic listening. Yet few systematic writings on psychoanalytic listening or technique provide comprehensive instruction that would prepare the analyst for the kind of analytic listening needed to participate imaginatively in this sort of intersubjective experience.Offering a short course in analytic listening, _Creative Listening and the Psychoanalytic Process_ provides a guide for the clinical (...)

    The University As Infrastructure of Becoming: Re-Activating Academic Freedom Through Humility in Times of Radical Uncertainty.Nicolas Zehner & Francisco Durán Del Fierro - forthcoming - Social Epistemology.
    Traditionally, the field of science and technology studies (STS) considered the scientific laboratory as the central site of knowledge production and technological development. While providing rich analyses of the social construction of scientific knowledge and the role of non-human actors, STS scholars have often neglected the university – the very context in which laboratories themselves are embedded – as a relevant object of research. In this paper, we argue for re-introducing the university as a relevant category and object of analysis (...)

Moreover, they do not act as legal persons or complete organizational actors all the time. Such settings give rise to a question that bears on the fundamental question of adequately identifying and assessing causal forces in social processes, namely: Who or what is responsible here?

    Superluminal transformations in complex Minkowski spaces.Ceon Ramon & Elizabeth A. Rauscher - 1980 - Foundations of Physics 10 (7-8):661-669.
    We calculate the mixing of real and imaginary components of space and time under the influence of superluminal boosts in thex direction. A unique mixing is determined for this superluminal Lorentz transformation when we consider the symmetry properties afforded by the inclusion of three temporal directions. Superluminal transformations in complex six-dimensional space exhibit unique tachyonic connections which have both remote and local space-time event connections.

    Theory of Stochastic Schrödinger Equation in Complex Vector Space.Kundeti Muralidhar - 2017 - Foundations of Physics 47 (4):532-552.
    A generalized Schrödinger equation containing correction terms to classical kinetic energy, has been derived in the complex vector space by considering an extended particle structure in stochastic electrodynamics with spin. The correction terms are obtained by considering the internal complex structure of the particle which is a consequence of stochastic average of particle oscillations in the zeropoint field. Hence, the generalised Schrödinger equation may be called stochastic Schrödinger equation. It is found that the second order correction terms (...)

    Quaternionic Quantum Dynamics on Complex Hilbert Spaces.Matthew A. Graydon - 2013 - Foundations of Physics 43 (5):656-664.
    We consider a quaternionic quantum formalism for the description of quantum states and quantum dynamics. We prove that generalized quantum measurements on physical systems in quaternionic quantum theory can be simulated by usual quantum measurements with positive operator valued measures on complex Hilbert spaces. Furthermore, we prove that quaternionic quantum channels can be simulated by completely positive trace preserving maps on complex matrices. These novel results map all quaternionic quantum processes to algorithms in usual quantum information theory.

    Social Network Analysis and Nutritional Behavior: An Integrated Modeling Approach.Alistair M. Senior, Mathieu Lihoreau, Jerome Buhl, David Raubenheimer & Stephen J. Simpson - 2016 - Frontiers in Psychology 7:172238.
    Animals have evolved complex foraging strategies to obtain a nutritionally balanced diet and associated fitness benefits. Recent research combining state-space models of nutritional geometry with agent-based models (ABMs), show how nutrient targeted foraging behavior can also influence animal social interactions, ultimately affecting collective dynamics and group structures. Here we demonstrate how social network analyses can be integrated into such a modeling framework and provide a practical analytical tool to compare experimental results with theory.

    ABSTRACT The philosophical tradition approaches to morals have their grounds predominantly on metaphysical and theological concepts and theories. Among the traditional ethics concepts, the most prominent is the Divine Command Theory (DCT). As per the DCT, God gives moral foundations to the humankind by its creation and through Revelation. Morality and Divinity are inseparable since the most remote civilization.

  39. Pressing the flesh: A tension in the study of the embodied, embedded mind.Andy Clark - 2008 - Philosophy and Phenomenological Research 76 (1):37–59.
    Mind, it is increasingly fashionable to assert, is an intrinsically embodied and environmentally embedded phenomenon. But there is a potential tension between two strands of thought prominent in this recent literature. One of those strands depicts the body as special, and the fine details of a creature’s embodiment as a major constraint on the nature of its mind: a kind of new-wave body-centrism. The other depicts the body as just one element in a kind of equal-partners dance between brain, body (...)

    A homeomorphism is built between the separable complex Hilbert space (quantum mechanics) and Minkowski space (special relativity) by meditation of quantum information (i.e. qubit by qubit). That homeomorphism can be interpreted physically as the invariance to a reference frame within a system and its unambiguous counterpart out of the system. The same idea can be applied to Poincaré’s conjecture (proved by G. Perelman) hinting at another way for proving it, more concise and meaningful physically. Furthermore, the conjecture (...)

    A hidden measurement representation for quantum entities described by finite-dimensional complex Hilbert spaces.Bob Coecke - 1995 - Foundations of Physics 25 (8):1185-1208.
    It will be shown that the probability calculus of a quantum mechanical entity can be obtained in a deterministic framework, embedded in a real space, by introducing a lack of knowledge in the measurements on that entity. For all n ∃ ℕ we propose an explicit model in $\mathbb{R}^{n^2 } $ , which entails a representation for a quantum entity described by an n-dimensional complex Hilbert space þn, namely, the “þn,Euclidean hidden measurement representation.” This Euclidean hidden measurement (...)

    Complex Vector Formalism of Harmonic Oscillator in Geometric Algebra: Particle Mass, Spin and Dynamics in Complex Vector Space.K. Muralidhar - 2014 - Foundations of Physics 44 (3):266-295.
    Elementary particles are considered as local oscillators under the influence of zeropoint fields. Such oscillatory behavior of the particles leads to the deviations in their path of motion. The oscillations of the particle in general may be considered as complex rotations in complex vector space. The local particle harmonic oscillator is analyzed in the complex vector formalism considering the algebra of complex vectors. The particle spin is viewed as zeropoint angular momentum represented by a bivector. (...)

    Technology led to more abstract causal reasoning.Peter Gärdenfors & Marlize Lombard - 2020 - Biology and Philosophy 35 (4):1-23.
    Many animal species use tools, but human technical engagement is more complex. We argue that there is coevolution between technical engagement and advanced forms of causal cognition in the human lineage. As an analytic tool, we present a classification of different forms of causal thinking. Human causal thinking has become detached from space and time, so that instead of just reacting to perceptual input, our minds can simulate actions and forces and their causal consequences. Our main thesis (...)

    Uniformity vs. Unity.Tatyana B. Lyubimova - 2019 - Russian Journal of Philosophical Sciences 62 (7):54-72.
    The question of whether it is possible to philosophize outside the categories of rationalist philosophy is not limited to methodology. It has ideological overtones. Namely, the rationalism that has developed in philosophy in modern times, after Descartes, is inevitably supplemented by mechanics. The world is seen as a machine, the living is reduced to mechanisms. Rationalism becomes a machine of mentality. Taking it as a model of normal thinking, giving it a universal value, we thereby impose Western way of thinking (...)

    Voice in the agentic assemblage.Lisa A. Mazzei & Alecia Y. Jackson - 2017 - Educational Philosophy and Theory 49 (11):1090-1098.
    In this article, we explore how a posthumanist stance has enabled us to work a different consideration of the way in which voice is constituted and constituting in educational inquiry; that is, we position voice in a posthuman ontology that is understood as attributable to a complex network of human and nonhuman agents that exceed the traditional understanding of an individual. Drawing on the work of Deleuze and Guattari, Barad, and Bennett, we present a research artifact that illustrates how (...)

    Computational complexity on computable metric spaces.Klaus Weirauch - 2003 - Mathematical Logic Quarterly 49 (1):3-21.
    We introduce a new Turing machine based concept of time complexity for functions on computable metric spaces. It generalizes the ordinary complexity of word functions and the complexity of real functions studied by Ko [19] et al. Although this definition of TIME as the maximum of a generally infinite family of numbers looks straightforward, at first glance, examples for which this maximum exists seem to be very rare. It is the main purpose of this paper to prove that, nevertheless, the (...)

    This article describes the theoretical foundations for researching game space and analytical methods focused on player reception of level design. It focuses primarily on games with open worlds and looks at environmental narratives within them. The methods discussed include game telemetry, mental mapping, and eye-tracking. Game worlds can be perceived as complex wholes that are important not only as the stage for game interactions, but also as sign structures carrying semantic meaning. These structures consist of spatial elements that (...)
