GENERALIZED IDEAL ELEMENTS IN le-Γ-SEMIGROUPS
Kostaq Hila, Edmond Pisha · Communications of the Korean Mathematical Society · 2011
In this paper we introduce and give some characterizations of (m, n)-regular le- ${\Gamma}$ -semigroup in terms of (m, n)-ideal elements and (m, n)-quasi-ideal elements. Also, we give some characterizations of subidempotent (m, n)-ideal elements in terms of $r_{\alpha}$ - and $l_{\alpha}$ - closed elements.
