Fixed point theorems for multi-valued contractive mappings and multi-valued Caristi type mappings. (English) Zbl 1094.47049
In this paper, the famous Banach contraction principle and Caristi’s fixed point theorem are generalized to the case of multi-valued mappings. The results are extensions of Nadler’s fixed point theorem and some Caristi type theorems for multi-valued operators.
