Relative T L-ideals in Semigroups

Abstract

In this paper, we investigate the notions of the left (right, twosided) ϕ − T L-ideals and (ϕ, σ) − T L-ideals in a semigroup, as well as some of their related properties. Furthermore, the results of relative T Lideals are applied to L-ideals of semigroups.
