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 $\text{dist}_Y(G_1(\xi),G_2(\xi))=0$.

Coupled coincidence point theorems for mixed monotone nonlinear operators

open access: yesComputers and Mathematics With Applications, 2012

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.
