On RelationQ in le- -Semigroups
Petraq Petro, Kostaq Hila, Jani Dine · 2016
In this paper we introduce and study the relationQ in le- -semigroups. This relation in general turns out to have better properties than the relationH studied in (10). We give several properties that hold in everyQ -class of an le- -semigroup and especially in everyQ -class satisfying the Green's condition. In particular, the -regularity and -intra-regularity of aQ -class is studied. We also consider a case aQ -class of an le- -semigroup M forms a subsemigroup of M = (M; ).
