Fixed point property and degree of coincidence

Applied General Topology
We introduce the concept of degree of coincidence to measure the divergence from the fixed point property in case a space does not have the FPP.

Coincidence and invariant approximation theorems for generalized f-nonexpansive multivalued mappings

International Journal of Mathematics and Mathematical Sciences, 2006
The main purpose of this paper is to prove some new coincidence and common fixed point theorems for noncommuting generalized f-nonexpansive multivalued mappings on non-starshaped domain in the framework of a Banach space.

Coincidence points of mappings and relations with applications [PDF]

Fixed Point Theory and Applications, 2012
We obtain coincidence points of mappings and relations under a contractive condition in a metric space. As applications, we achieve an existence and uniqueness theorem of solution for a general class of nonlinear integral equations. 2010 Mathematics Subject Classification: 47H10; 54H25; 54C60.

Coincidence Point, Best Approximation, and Best Proximity Theorems for Condensing Set-Valued Maps in Hyperconvex Metric Spaces

Fixed Point Theory and Applications, 2009
In hyperconvex metric spaces, we first present a coincidence point theorem for condensing set-valued self-maps. Then we consider the best approximation problem and the best proximity problem for set-valued mappings that are condensing. As an application,

Continuous Dependence of Coincidence Points on a Parameter

Set-Valued and Variational Analysis, 2014
The coincidence points existence problem with a parameter is considered. Sufficient conditions for dependence of a coincidence point on a parameter to be continuous, Hölder continuous or Lipschitz continuous are obtained. © 2014, Springer Science+Business Media Dordrecht.

Coincidences and fixed points of reciprocally continuous and compatible hybrid maps

International Journal of Mathematics and Mathematical Sciences, 2002
It is proved that a pair of reciprocally continuous and nonvacuously compatible single-valued and multivalued maps on a metric space possesses a coincidence.

On the Existence of Coincidence and Common Fixed Point of Two Rational Type Contractions and an Application in Dynamical Programming

Journal of Function Spaces, 2016
We establish some coincidence point results for self-mappings satisfying rational type contractions in a generalized metric space. Presented coincidence point theorems weaken and extend numerous existing theorems in the literature besides furnishing some

Caristi Type Coincidence Point Theorem in Topological Spaces

Journal of Applied Mathematics, 2013
A generalized Caristi type coincidence point theorem and its equivalences in the setting of topological spaces by using a kind of nonmetric type function are obtained.
