A generalized coincidence point index

open access: diamondApplied General Topology, 2005
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

Remarks on some coupled coincidence point results in partially ordered metric spaces

open access: hybridArab Journal of Mathematical Sciences, 2014
In this paper we have used a method of reducing coupled coincidence and coupled fixed point results in partially ordered metric spaces to the respective results for mappings with one variable, even obtaining (in some cases) more general theorems.

Fixed point results of weakly contraction mappings in partially ordered b-metric spaces

open access: yesBMC Research Notes, 2022
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.

Coincidence Point of Edelstein Type Mappings in Fuzzy Metric Spaces and Application to the Stability of Dynamic Markets

open access: yesAxioms, 2023
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

open access: yesBMC Research Notes, 2021
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.

open access: yesBMC Research Notes, 2020
Objectives The aim of this paper is to establish some fixed point, coincidence point and, coupled coincidence and coupled common fixed point results for generalized $$(\phi , \psi )$$ ( ϕ , ψ ) -contractive mappings in partially ordered b-metric spaces ...

Note on KKM maps and applications

open access: yesFixed Point Theory and Applications, 2006
We apply the KKM technique to study fixed point theory, minimax inequality and coincidence theorem. Some new results on Fan-Browder fixed point theorem, Fan's minimax theorem and coincidence theorem are obtained.

Algebraic Coincidence Periods Of Self – Maps Of A Rational Exterior Space Of Rank 2

open access: yesمجلة بغداد للعلوم, 2010
Let f and g be a self – maps of a rational exterior space . A natural number m is called a minimal coincidence period of maps f and g if f^m and g^m have a coincidence point which is not coincidence by any earlier iterates.

Fixed point results of $(\phi,\psi)$-weak contractions in ordered $b$-metric spaces

open access: yesCubo, 2022
The purpose of this paper is to prove some results on fixed point, coincidence point, coupled coincidence point and coupled common fixed point for the mappings satisfying generalized $(\phi, \psi)$-contraction conditions in complete partially ordered ...

Probabilistic (ω,γ,ϕ)-contractions and coupled coincidence point results

open access: yesAIMS Mathematics, 2021
In this paper, we introduce the notion of probabilistic $ (\omega, \gamma, \phi) $-contraction and establish the existence coupled coincidence points for mixed monotone operators subjected to the introduced contraction in the framework of ordered Menger $
