Abstract : 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 subid-empotent $(m,n)$-ideal elements in terms of $r_{\alpha}$- and $l_{\alpha}$- closed elements.
