Abstract

It is known, that the class of all BCK-algebras enjoys the strong amalgamation property . Here we present some results concerning the amalgamation property for some subclasses of the class of all BCK-algebras. The notations and the terminology used in this paper are rather standard. For a background on universal algebra we refer the reader to G. Gr¨atzer [2] and for BCK-algebras to K. Is´eki and S. Tanaka [4]. We let N = {0, 1, . . .} and N+ = N\{0}
