Some Closure Operators and Topologies on a Hyper BCK-algebra.

Given a hyper BCK-algebra (H, *, 0), we introduce some subsets of H and use them to generate two closure operators on H. In this paper, we show that each of the two closure operators on H can be utilized to form a base for some topology on H. Moreover, we show that each of the induced topologies coincides with a previously known topology on a hyper BCK-algebra. [ABSTRACT FROM AUTHOR]
