Abstract

We introduce notions of interior and closure of a set about a subbase for a topological space, and obtain their basic properties ; In addition, we discuss the relations between rough sets and subsets of a topological space. These results can be considered as fundamental theory of rough sets.

Key words

topology / rough set / interior / closure
