Here, being motivated from the works of Zhu, Guo and Shum on left Clifford semigroups, we have introduced left k-Clifford semirings as a generalization of k-Clifford semirings. A k-regular semiring S ∈ SL + is a left k-Clifford semiring (left k-semifield) if for all a ∈ S, aS ⊆ Sa (for all b ∈ S , a ∈ Sb). Several characteristics for this class of semirings are obtained. Moreover a semiring is left k-Clifford if and only if it is a distributive lattice of left k-semifields.Keywords: k-regular semiring; left k-semifield; left k-Clifford semiring; distributive lattice of left k-semifields.
