Metric conditions, graphic contractions and weakly Picard operators

Studia Universitatis Babes-Bolyai Matematica
In the paper of S. Park (\emph{Almost all about Rus-Hicks-Rhoades maps in quasi-metric spaces}, Adv. Theory Nonlinear Anal. Appl., {\bf 7}(2023), No. 2, 455-472), the author solves the following problem: \emph{Which metric conditions imposed on \(f\) imply that \(f\) is a graphic contraction?}In this paper we study the following problem: \emph{Which ...

Ulam-Hyers stability of singular integral equations, via weakly Picard operators

Fixed Point Theory, 2016
In this paper we investigate the Ulam-Hyers stability of several integral equations with singularity. First we give some results concerning the Ulam-Hyers stability of integral equations with weak singularities. Our approach is also suitable for studying some fractional di erential equations.

Data dependence for some integral equation via weakly Picard operators

2004
Summary: In this paper we study data dependence for the following integral equation: \[ u(x)=h(x,u(a))+\int^{x_1}_{a_1}\dots\int^{x_m}_{a_m}K(x,s,u(s))ds,x\in\prod^m_{i=1}[a_i,b_i] \] by using \(c\)-WPOs.
