Abstract :
In the present paper, we introduce the notions of beta-type and beta gamma-type multi-valued contractive mappings in a Menger PbM-space and obtain some new fixed point theorems for both beta-admissible and (beta,gamma)-admissible mappings. Our results extensively generalize previous results in this framework. Furthermore, we support our results by some non-trivial examples and an application.
