We introduce the k-radicals of Green's relations in semirings with a semilattice additive reduct, introduce the notion of left k-regular (right k-regular) semirings and characterize these semirings by k-radicals of Green's relations. We also characterize the semirings which are distributive lattices of left k-simple subsemirings by k-radicals of Green's relations.
Keywords: k-radicals of Green's relations, left k-regular semiring, left k-simple semiring, distributive lattices of left k-simple semirings
