Remarks on the paper "Treatment of Set-Valued Robustness via Separation and Scalarization"

Abhik Digar, Kuntal Som

In this paper, we remark on the published paper "Treatment of Set-Valued Robustness via Separation and Scalarization" [1], which deals with the robust solution to an uncertain cons…

Best approximations in metric spaces with property strongly UC

Abhik Digar

In this article, we introduce a geometrical notion, property strongly UC which is stronger than property UC and prove the existence of best approximations for a new class of almost…

Characterizations of strictly convex spaces and proximal uniform normal structure

Abhik Digar, G. Sankara Raju Kosuru

We provide a few characterizations of a strictly convex Banach space. Using this we improve the main theorem of [Digar, Abhik; Kosuru, G. Sankara Raju; Cyclic uniform Lipschitzian…

On proximal uniform normal structure and relatively nonexpansive mappings

Abhik Digar, G. Sankara Raju Kosuru

The main objective of this article is to provide an alternative approach to the central result of [Eldred, A. Anthony, Kirk, W. A., Veeramani, P., Proximal normal structure and rel…

A Characterization of Weak Proximal Normal Structure and Best Proximity Pairs

Abhik Digar, Rafael Espínola García, G. Sankara Raju Kosuru

The aim of this paper is to address an open problem given in [Kirk, W. A., Shahzad, Naseer, Normal structure and orbital fixed point conditions, J. Math. Anal. Appl. {\bf{vol 463(2…

Global optimization on a metric space with a graph and an application to PBVP

Abhik Digar, G. S. Raju K

In this article we introduce a new type of cyclic contraction mapping on a pair of subsets of a metric space with a graph and prove best proximity points results for the same. Also…
