Abstract

The main outcome of this paper is to introduce the notion of orthogonal gauge spaces and to present some related fixed-point results. As an application of our results, we obtain existence theorems for integral equations.

Highlights

  • Fixed-point theory is a very important tool for proving the existence and uniqueness of the solutions to various mathematical models, such as integral and partial differential equations, optimization, variational inequalities, and approximation theory

  • Gordji et al [6] introduced an exciting notion of the orthogonal sets after which, orthogonal metric spaces were introduced. e concept of a sequence, continuity, and completeness has been redefined in this space

  • They gave an extension of the Banach fixed-point theorem on this newly described shape and applied their theorem to show the existence of a solution for a differential equation, which cannot be applied by the Banach fixed-point theorem

Summary

Introduction

Fixed-point theory is a very important tool for proving the existence and uniqueness of the solutions to various mathematical models, such as integral and partial differential equations, optimization, variational inequalities, and approximation theory. E concept of a sequence, continuity, and completeness has been redefined in this space They gave an extension of the Banach fixed-point theorem on this newly described shape and applied their theorem to show the existence of a solution for a differential equation, which cannot be applied by the Banach fixed-point theorem. In 2013, Ali et al [18] ensured the existence of fixed points for an integral operator via a fixed-point theorem on complete gauge spaces. In 2012, Wardowski [19] gave a new type of contractions, named as F-contractions, and established new related fixed-point results. We apply the concept of orthogonality in gauge spaces and investigate the existence of solutions of integral equations through the fixed-point theorem on orthogonal complete gauge spaces
