On &i&M&/i&-Asymmetric Semi-Open Sets and Semicontinuous Multifunctions in Bitopological Spaces

摘要

The purpose of this paper is to introduce the notions of m -asymmetric semiopen sets and M -asymmetric semicontinuous multifunctions defined between asymmetric sets satisfying certain minimal conditions in the framework of bitopological spaces. Some new characterizations of m -asymmetric semiopen sets and M -asymmetric semicontinuous multifunctions will be investigated and several fundamental properties will be obtained.
