Exact BCK-sequence in BCK-algebra

摘要

The notion of quasi BCK-exact sequence of modules was introduced by B.Davvaz and coauthors in 1999 as a generalization of the notion of exact sequence. In 2016 S.Asawasamrit & C.Promsakon introduced Quasi-Commutative KK-algebra [14]. In this paper we investigate further this notion on BCK-algebra. In particular, some interesting results concerning this concept and torsion functor on BCK-algebra are given.
