Study of Existence and Stability of Fixed Points of Hypotenuse Contracting Mappings with Applications to Parabolic PDE

Kushal Roy, Anish Banerjee, Lakshmi Kanta Dey

In this article, we introduce a novel class of mappings identified by their property of contracting the hypotenuse of a right-angled triangle in the setting of metric spaces. We es…

Unlocking novel topological structures via rough families

Sourav Mandal, Lakshmi Kanta Dey, Pratikshan Mondal

Very recently, the notion of rough family has been introduced in [Leonetti, P., J. Convex Anal. 32(4):1083-1090, 2025] to explore rough ideal convergence in topological spaces wher…

On the geometry of -norm

Lakshmi Kanta Dey, Subhadip Pal

Let and be Banach spaces and let with . We study the geometry of -(semi-)norm on , defined by \[ \|T\|_G := \inf_{δ>0}\sup\{\|Tx\|: \|x\|…

Best Proximity Point Results for Perimetric Contractions

Hiranmoy Garai, Evgeniy Petrov, Pratikshan Mondal +1

This paper has two aims, first one is to introduce special kind of proximal contractions guaranteeing a finite number of best proximity points, and second one is to derive best pro…

On a novel approach to nonexpansive mappings

Anish Banerjee, Hiranmoy Garai, Pratikshan Mondal +1

This paper seeks to advance the theory of nonexpansive mappings by introducing and exploring a novel class of nonexpansive type mappings, which we aptly designate as perimetric non…

Perimetric contraction on quadrilaterals and related fixed point results

Anish Banerjee, Pratikshan Mondal, Lakshmi Kanta Dey

In this article, we introduce a four-point analogue of Banach-type, Kannan-type, and Chatterjea-type contractions, and examine their properties. We establish sufficient conditions…
