Abstract

The aim of this work is to usher in tripled b-metric spaces, triple weakly alpha _{s}-admissible, triangular partially triple weakly alpha _{s}-admissible and their properties for the first time. Also, we prove some theorems about coincidence and common fixed point for six self-mappings. On the other hand, we present a new model, talk over an application of our results to establish the existence of common solution of the system of Volterra-type integral equations in a triple b-metric space. Also, we give some example to illustrate our theorems in the section of main results. Finally, we show an application of primary results.

Highlights

  • Introduction and preliminaries TheBanach contraction principle plays a central part in metric fixed point theory, and a great number of researchers revealed many fruitful generalizations of this resolution in diverse ways

  • Numerous research articles have been published comprising fixed point theorems for several classes of single-valued and multi-valued operators in b-metric spaces

  • In 2012, the concept of F-contraction, which is one of these generalizations, was introduced by Wardowski [7]. He presented that every F-contraction defined in a complete metric space has a unique fixed point

Summary

Uniqueness of limit gives that

is only possible solution. Similarly, the pair (g, S2) and (h, S3) is αs-compatible. To prove that (f , g, h) is a partially weakly αs-admissible triple of mappings with respect to S!, let x ∈ X and y ∈ S1–1(g(f (x))), that is, S1(y) = g(f (x)) and e6y – 1 = g ln x 1+

Thus y
Thus we have
