In this paper, the concept of L-fuzzy soft sets based on complete Boolean lattices, which can be seen as a generalization of fuzzy soft sets, is introduced. The topological and lattice structure of L-fuzzy soft sets are obtained. Some operations on L-fuzzy soft sets are discussed, and new types of L-fuzzy soft sets such as full, keeping intersection and keeping union L-fuzzy soft sets are defined and supported by some illustrative examples. A pair of L-fuzzy soft rough approximations is proposed and their properties are given. Based on L-fuzzy soft rough approximations, the concept of L-fuzzy soft rough sets is introduced and their structures are studied. The fact that every finite L-fuzzy topological space is an L-fuzzy soft approximation space is revealed. In addition, we obtain two one-to-one correspondence relationships associated with L-fuzzy soft sets, which expounds the broad application prospect of L-fuzzy soft sets.
