Abstract

In this paper, we introduce and study the concepts of semicontinuous mappings, α–
continuous mappings, semiopen mappings and α–open mappings in fuzzifying bitopological spaces.
The characterizations of these mappings along with their relationship with certain other mappings
are investigated.
