On Fuzzy k-ideals and Anti-fuzzy k-ideals in Γ-hemi-rings

In this paper,introducing the concept of fuzzy k-ideals and anti-fuzzy k-ideals of Γ-hemi-rings,we discuss and investigate some of its properties.

Characterizations of Hemirings by the Properties of Their <i>k</i>-Ideals

In this paper we characterize those hemirings for which each k-ideal is idempotent. We also characterize those hemirings for which each fuzzy k-ideal is idempotent. The space of prime k-ideals (fuzzy k-prime k-ideals) is topologized.
