Abstract

Our aim is to introduce the notion of a parametric $N_{b}$-metric and study some basic properties of parametric $N_{b}$-metric spaces. We give some fixed-point results on a complete parametric $N_{b}$-metric space. Some illustrative examples are given to show that our results are valid as the generalizations of some known fixed-point results. As an application of this new theory, we prove a fixed-circle theorem on a parametric $N_{b}$ -metric space.

Keywords: parametric $N_{b}$-metric, \'{C}iri\'{c}'s fixed-point result, Kannan's fixed-point result, Chatterjea's fixed-point result, expansive mapping, fixed circle
