JH-Operators and Occasionally Weakly g-Biased Pairs in Fuzzy Symmetric Spaces

We introduce the notions of -operators and occasionally weakly -biased mappings in fuzzy symmetric spaces to prove common fixed point theorems for self-mappings satisfying a generalized mixed contractive condition. We also prove analogous results for two pairs of -operators by assuming symmetry only on the set of points of coincidence. These results unify, extend and complement many results existing in the recent literature. We give also an application of our results to product spaces.
