Ulam–Hyers–Rassias stability problem for several kinds of mappings

Afrika Matematika, 2012
Let \(f\) maps a (topological) vector space into a Banach space and let \(\alpha,\beta\) be given scalars. The stability of functional equations of the form \[ f(\alpha(x+y))+f(\beta(x-y))=(\alpha+\beta)f(x)+(\alpha-\beta)f(y) \] is considered.

Ulam-Hyers-Rassias stability for stochastic integral equations of Volterra type

2019
In this paper, we study the Ulam--Hyers--Rassias stability for stochastic integral equations of Volterra type by using fixed point theorem and Pachpatte's inequality.

An investigation into the characteristics of VFIDEs with delay: solvability criteria, Ulam–Hyers–Rassias and Ulam–Hyers stability

The Journal of Analysis
The authors analyze an integro-differential equation of Volterra-Fredholm type with delay. The Banach contraction principle is used to deduce sufficient conditions for the existence and uniqueness of the solution, as well as to study Ulam-Hyers-Rassias and Ulam-Hyers stabilities.

Ulam-Hyers-Rassias stability of Caputo fractional differential equations with deviating arguments on unbounded intervals

Mathematica Slovaca
Abstract In this paper, we investigate the Ulam-Hyers-Rassias stability of non-local problems for differential equations with Caputo fractional derivatives involving deviating arguments on unbounded intervals. By applying the Banach fixed-point theorem, we establish conditions for the existence and uniqueness of mild solutions within ...
