Research into the geometric properties of Banach spaces and metric spaces has long provided profound insights into the architecture of functional analysis and the intrinsic nature of various spatial ...

Abstract.In this paper, we state a new form of fixed point theorems on metric spaces and 2-metric spaces which unifies and generalizes many results in the literature. Examples are given to illustrate ...

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 ...
