The variational principle of fixed point theorems in certain fuzzy topological spaces

P. Balasubramaniam and S. Murali Sankar

Abstract:

The main purpose of this paper is to introduce the concept of $F$-type fuzzy topological spaces. Further variational principle and Caristi's fixed point theorem have been extended in the $F$-type fuzzy topological spaces.
