Semilattice Co-Congruence in $\Gamma$-Semigroups

Abstract

As a generalization of semigroups, Sen, in 1981, introduced the concept of $\Gamma$-semigroups. In the author's paper (D A. Romano. $\Gamma$-semigroups with apartness. \emph{Bull. Allahabad Math. Soc.}, 34(1)(2019), 71--83.) it is introduced and analyzed the concept of $\Gamma$-semigroups with apartness in Bishop's constructive framework. In this article, as a continuation of previous research, the concept of co-congruences in $\Gamma$-semigroups is introduced and analyzed. Additionally, it is investigated (co-ordered) semilattice co-congruence on (co-ordered) $\Gamma$-semigroup with apartness.
