A generalized coincidence point index
The paper is devoted to build for some pairs of continuous single-valued maps a coincidence point index. The class of pairs (f, g) satisfies the condition that f induces an epimorphism of the Cech homology groups with compact supports and coefficients in

A Random Coincidence Point Theorem
Let \((\Omega ,\Sigma)\) be a measurable space, \(M\) a weakly compact subset of a Banach space \(X\), \(f:\Omega\times M\to M\) and \(T:\Omega\times M\to 2^{M}\) random operators. The main result of this note gives sufficient conditions for the existence of a random coincidence point of \(T\) and \(f\), i.e., a measurable mapping \(\xi:\Omega\to M ...

New Quasi-Coincidence Point Polynomial Problems [PDF]
Let F:ℝ×ℝ→ℝ be a real-valued polynomial function of the form F(x,y)=as(x)ys+as-1(x)ys-1+⋯+a0(x), where the degree s of y in F(x,y) is greater than or equal to 1.

New Existence Results and Generalizations for Coincidence Points and Fixed Points without Global Completeness [PDF]
Some new existence theorems concerning approximate coincidence point property and approximate fixed point property for nonlinear maps in metric spaces without global completeness are established in this paper.

In this paper, we prove a coincidence point result for a pair of mappings satisfying Edelstein-type contractive condition on fuzzy metric spaces. We describe the equilibrium of a simple demand–supply model of a dynamic market by the coincidence point of ...

A note on noncompact collectively coincidence point theory
AbstractIn this paper we present a variety of collectively fixed point and coincidence point results where the maps are not necessarily compact. Our arguments are based on a very general fixed point result in the literature.

Approximate Coincidence Point of Two Nonlinear Mappings
We study the approximate coincidence point of two nonlinear functions introduced by Geraghty in 1973 and Mizoguchi and Takahashi (ℳ𝒯-function) in 1989.

Fixed point results of weakly contraction mappings in partially ordered b-metric spaces
Objectives We explored the results of fixed point, coincidence point and coupled coincidence point for the mappings in an ordered metric spaces. Our results generalized and extended the well-known results in the literature.

Fixed point results for weak contractions in partially ordered b-metric space
Objectives We explore the existence of a fixed point as well as the uniqueness of a mapping in an ordered b-metric space using a generalized $$({\check{\psi }}, \hat{\eta })$$ ( ψ ˇ , η ^ ) -weak contraction.

Coincident-point rigidity in normed planes
A bar-joint framework $(G,p)$ is the combination of a graph $G$ and a map $p$ assigning positions, in some space, to the vertices of $G$. The framework is rigid if every edge-length-preserving continuous motion of the vertices arises from an isometry of the space.
