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.

Nonunique Coincidence Point Results via Admissible Mappings [PDF]
This paper is aimed at presenting some coincidence point results using admissible mapping in the framework of the partial b-metric spaces. Observed results of the article cover a number of existing works on the topic of “investigation of nonunique fixed ...

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

Coincidence point theorems for multivalued mappings [PDF]
Some new coincidence point and fixed point theorems for multivalued mappings in complete metric space are proved. The results presented in this paper enrich and extend the corresponding results in [5-16, 20-25, 29].

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.

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 ...

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 ...

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.
