Relationships between Alexandrov (fuzzy) topologies and upper approximation operators

Yong Chan Kim

Abstract

In this paper, we investigate the properties of Alexandrov (fuzzy) topologies, fuzzy preorders and upper approximation operators in complete residuated lattices. Moreover, we investigate the relations among Alexandrov (fuzzy) topologies, fuzzy preorders and upper approximation operators. We give their examples.
