本文引入了基于完备布尔格的L-fuzzy软集的概念,它可以看作是模糊软集的推广。给出了L-fuzzy软集的拓扑结构和格结构。讨论了L-fuzzy软集上的一些运算,定义了新的L-fuzzy软集类型,如满L-fuzzy软集、保交L-fuzzy软集和保并L-fuzzy软集,并给出了一些实例.提出了一对L-fuzzy软粗糙逼近,并给出了它们的性质。在L-fuzzy软粗糙近似的基础上,引入了L-fuzzy软粗糙集的概念,研究了它们的结构。证明了每个有限L-fuzzy拓扑空间都是L-fuzzy软逼近空间。此外,我们还得到了与L-fuzzy软集相关的两个一一对应关系,从而阐明了L-fuzzy软集广泛的应用前景。
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.
