Coincidence point theorems for generalized contractions with application to integral equations
, 2015 In this article, we introduce a new type of contraction and prove certain coincidence point theorems which generalize some known results in this area. As an application, we derive some new fixed point theorems for F-contractions.

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 Point Sets in Digital Topology [PDF]
arXiv, 2019 In this article, we investigate some properties of the coincidence point set of digitally continuous maps. Following the Rosenfeld graphical model which seems more combinatorial than topological, we expect to achieve results that might not be analogous to the classical topological fixed point theory.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Due to the tight curvature in their design, ring applicators are usually associated with large positioning errors. The standard practice to correct for these deviations based on global offsets may not be sufficient to comply with the recommended tolerance.

New coincidence point and fixed point theorems for essential distances and $e^{0}$-metrics [PDF]
arXiv, 2019 In this paper, we establish some new fixed point theorems and coincidence point theorems for essential distances and $e^{0}$-metrics which generalize and improve Berinde-Berinde's fixed point theorem, Mizoguchi-Takahashi's fixed point theorem, Nadler's fixed point theorem and Banach contraction principle and many known results in the literature.

, 2015 In this paper, we introduce the concepts of weak g-graph-preserving for multi-valued mappings and weak G-contractions in a metric space endowed with a directed graph.

A principle of randomization for coincidence points with applications
Applied Mathematics Letters, 1999 AbstractIn this paper, a randomizing theorem of coincidence points for set-valued mappings is shown. As applications, we utilize this result to obtain some new random coincidence points theorems.

Fixed points and coincidence points for multimaps with not necessarily bounded images [PDF]
Fixed Point Theory and Applications, 2004 In metric spaces, single-valued self-maps and multimaps with closed images are considered and fixed point and coincidence point theorems for such maps have been obtained without using the (extended) Hausdorff metric, thereby generalizing many results in the literature including those on the famous conjecture of Reich on multimaps.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study aims to evaluate the accuracy of the frameless linear accelerator‐based stereotactic radiosurgery (FSRS) system incorporating cone‐beam CT (CBCT), six degrees of freedom (6‐DoF) couch, room laser, and surface image‐guided (SG) systems.
