Fuzzy Inverse Semigroup Congruence on Semigroups

摘要

The aim of this paper is to study a class of fuzzy congruence on' semigroup, that is, fuzzy inverse semigroup congruence, after introducing the concept of fuzzy weak seminormal subsemigroup of semigroup, we show that there is an one-to-one correspondence between the fuzzy weak seminormal subsemigroup and the fuzzy inverse semigroup congruence on a semigroup.
