摘要

A new concept of set-valued Mizoguchi-Takahashi G -contractions is introduced in this paper and some fixed point theorems for such mappings in b -metric spaces endowed with directed graphs are established under some sufficient conditions. Our results improve and extend those of [20] and [24]. We also give some examples supporting our main results. As an applications, we prove the existence of fixed points for multivalued mappings satisfying generalized MT-contractive condition in ε-chainable b -metric spaces and the existence of a solution for some integral equations.
