In this paper, a new type of graph contractive multi-valued mappings in a metric space with a directed graph is introduced and studied. A common fixed point theorem of those two multi-valued mappings ...

Operator algebras and functional analysis form a foundational framework in modern mathematics, interlinking abstract algebraic structures with analytic techniques to study infinite‐dimensional spaces.

The paper introduces a generalized concept of the cluster points of multi-function as a unified approach to the study of selection theorems, closed graph theorems and minimal multi-functions. The ...
