A Further Study on L-Fuzzy Covering Rough Sets
Yaoliang Xu, Dan-dan Zou, Lingqiang Li · Journal of Mathematics and Informatics · 2022
For L L = ∗ → ( , , ) a complete residuated lattice, a type of L -fuzzy covering rough sets was defined by Li [8] in 2017. In this paper, a further study on rough sets was given. Precisely, a single axiomatic characterization of the L -fuzzy covering rough sets was presented, and the relationships between the -fuzzy covering rough sets and L -fuzzy relation rough sets were established.
