Subfixed Point for Generalized Contraction Family of Fuzzy Mappings
We say that [[mu].sup.*] [member of] F(X) is a subfixed point of the mapping f: F(X) [arrow right] F(X) if and only if [[mu].sup.*] [subset or equal to] f([[mu].sup.*]).
In the next two theorems we consider the existence of a fuzzy set [[mu].sup.*] which represents a common subfixed point for the family of self-mappings {[f.sub.i]}, that is, the point such that [[mu].sup.*] [subset or equal to] [f.sub.i]([[mu].sup.*]) for all i [member of] N.
