Analysis of JS-contractions with applications to fractional boundary value problems

Abstract

AbstractIn this article, we modify JS-contractions by weakening the conditions on the function θ, where $\theta : ( 0,\infty ) \rightarrow ( 1,\infty ) $ θ : ( 0 , ∞ ) → ( 1 , ∞ ) is a strictly increasing function. We prove fixed-point results for obtained contractions. Some examples are given to validate the results and modifications. We use our main theorem to establish the existence results for the solutions of the Atangana–Baleanu–Caputo fractional boundary value problem with integral boundary conditions. We also present a new definition of θ-Ulam stability and find the stability of our fractional boundary value problem.
