摘要
Various fuzzy generalizations of rough approximations have been proposed in the literature. This paper is devoted to the discussion of the relationship between L-fuzzy rough sets and L-topologies on an arbitrary universe. Finally, one-to-one correspondence between the set of all reflexive, transitive L-relations and the set of all Alexandrov L-topologies is obtained. (C) 2011 Elsevier B.V. All rights reserved.
