On ordered bi-G-ideals in ordered G-semigroups

摘要

In this paper, an equivalence relation B_m~n on an ordered Γ-semigroup S is introduced. Using the relation B_m~n, 0-minimal (m, n)-Γ-ideals of S is studied. The results obtained generalize the results on semigroups(without order) and G-semigroups(without order).
