Abstract
L-fuzzy soft set is a generalization of fuzzy soft set. In the recent paper L-fuzzy soft sets have emerged as a new tool to characterize semirings. Concepts of L-fuzzy soft subsemirings and L-fuzzy ideals are introduced and some of their properties are studied. It is seen that L-fuzzy soft ideals have ability to characterize regular and weakly regular semirings. Finally fully idempotent semirings are characterized with the help of L-fuzzy soft ideals.
