A characterization of weak proximal normal structure and best proximity pairs [PDF]

open access: yesRevista de la Real Academia de Ciencias Exactas, Físicas y Naturales. Serie A. Matemáticas, 2022
The aim of this paper is to address an open problem given in [Kirk et al. in J Math Anal Appl 463:461–476, (2018)]. We give a characterization of weak proximal normal structure using best proximity pair property.

Proximinal Retracts and Best Proximity Pair Theorems

Numerical Functional Analysis and Optimization, 2003
Abstract This note is concerned with proximinality and best proximity pair theorems in hyperconvex metric spaces and in Hilbert spaces. Given two subsets A and B of a metric space and a mapping best proximity pair theorems provide sufficient conditions that ensure the existence of an such that Thus such theorems provide optimal approximate solutions in

Best proximity pairs and equilibrium pairs for Kakutani multimaps

Nonlinear Analysis: Theory, Methods & Applications, 2009
New existence theorems of best proximity pairs for a finite family of Kakutani multimaps are proved in a normed space setting. As applications, new existence theorems of equilibrium pairs for free n-person and 1-person games are obtained. Our results generalize and improve several well-known results. © 2008 Elsevier Ltd.
