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

open access: yesFixed Point Theory and Applications, 2008
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,

On fixed point theorems for ordered contractions with applications

open access: yesAIMS Mathematics
The purpose of this paper is to prove some fixed point theorems for ordered contractions in partially ordered $ b $-metric spaces. We consider several common fixed point and coincidence point results for four mappings in such spaces. The results obtained

Coincidence and fixed points for hybrid strict contractions

open access: yesJournal of Mathematical Analysis and Applications, 2004
The author slightly generalizes a condition introduced by \textit{M. Aamri} and \textit{D. El Moutawaki} [ibid. 270, 181--188 (2002; Zbl 1008.54030)] relaxing the commutativity of two mappings to obtain a coincidence theorem for set-valued mappings.

Coupled Coincidence Point and Coupled Common Fixed Point Theorems in Partially Ordered Metric Spaces with -Distance

open access: yesFixed Point Theory and Applications, 2010
We introduce the concept of a -compatible mapping to obtain a coupled coincidence point and a coupled point of coincidence for nonlinear contractive mappings in partially ordered metric spaces equipped with -distances.
