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

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.

Existence of common coincidence point of intuitionistic fuzzy maps

Journal of Intelligent & Fuzzy Systems, 2018
The aim of this paper is mainly to find the existence of a common coincidence point for three intuitionistic fuzzy set-valued maps in the context of (α, β) - level sets of an intuitionistic fuzzy set.

ON POINTS OF COINCIDENCE OF TWO MAPPINGS

Mathematics of the USSR-Sbornik, 1981
This paper is devoted to the coincidence theory of two continuous mappings.A definition is given, in cohomological terms, of the coincidence index of two continuous mappings , where and are connected (not necessarily compact), orientable, -dimensional topological manifolds without boundary, is a compact mapping and is a proper mapping.Invariance ...

A Browder-Petryshyn coincidence point theorem

Modern Mathematical Methods
Let $C$ be a subset of a Hilbert space, and let $f$ and $g$ be self-maps on $C$ such that the range of $f$ is a convex, closed, and bounded subset of the range of $g$. If $f$ does not increase distances more than $g$, we demonstrate that $f$ and $g$ have
