Existence of a solution for a nonlinear integral equation by nonlinear contractions involving simulation function in partially ordered metric space

Abstract

In a recent paper, Khojasteh et al. presented a new collection of simulation functions, said Z-contraction. This form of contraction generalizes the Banach contraction and makes different types of nonlinear contractions. In this article, we discuss a pair of nonlinear operators that applies to a nonlinear contraction including a simulation function in a partially ordered metric space. For this pair of operators with and without continuity, we derive some results about the coincidence and unique common fixed point. In the following, many known and dependent consequences in fixed point theory in a partially ordered metric space are deduced. As well, we furnish two interesting examples to explain our main consequences, so that one of them does not apply to the principle of Banach contraction. Finally, we use our consequences to create a solution for a particular type of nonlinear integral equation.

A simulation function approach for optimization by approximate solutions with an application to fractional differential equation

“…In the following, Karapınar et al [19] offered the best proximity point results using the simulation functions. Until now, several papers have been published in this field; see [6,9,10,15,16,25]. In this work, using a contraction function via simulation function defined by Roldán et al [32], we prove the existence and uniqueness of a common best proximity point for a pair of nonself functions that are not necessarily continuous.…”
