Coincidence Points and Generalized Coincidence Points of Two Set-Valued Mappings

Proceedings of the Steklov Institute of Mathematics, 2020
Let $(X,\rho_X)$ and $(Y,\rho_Y)$ be metric spaces and $G_i$, $i=1,2$ be mappings from $X$ to the collection of nonempty closed subsets of $Y$. Recall that a point $\xi\in X$ is called a coincidence point of $G_1$ and $G_2$ if $G_1(\xi)\cap G_2(\xi)\ne \emptyset$ and a generalized coincidence point if $\text{dist}_Y(G_1(\xi),G_2(\xi))=0$.

Around metric coincidence point theory

Studia Universitatis Babes-Bolyai Matematica, 2023
Let $(X,d)$ be a complete metric space, $(Y,\rho)$ be a metric space and $f,g:X\to Y$ be two mappings. The problem is to give metric conditions which imply that, $C(f,g):=\{x\in X\ |\ f(x)=g(x)\}\not=\emptyset$. In this paper we give an abstract coincidence point result with respect to which some results such as of Peetre-Rus (I.A.

A coincidence point theorem for densifying mappings

Publicationes Mathematicae Debrecen, 1994
The main result is an interesting coincidence point theorem for densifying maps. Several corollaries are also derived. The main result unifies and extends several known results. To illustrate the theorem a suitable example is given.

Kantorovich’s Fixed Point Theorem in Metric Spaces and Coincidence Points

Proceedings of the Steklov Institute of Mathematics, 2019
The authors prove existence and uniqueness of fixed points of a self-mapping on a complete metric space, generalizing and improving the well-known Kantorovich's fixed point theorem in the setting of Banach spaces. Besides of a standard self-mapping, the authors also obtain coincidence point theorems for set-valued mappings on metric spaces.
