Abstract

In this paper, some fuzzy fixed point theorems for fuzzy mappings are established by considering the nonempty closed -cut sets. Some importance observations are also discussed. Our results clearly extend, generalize and improve the corresponding results in the literatures, which have given most of their attention to the class of fuzzy sets with nonempty compact or closed and bounded -cut sets.
