Impulsive fractional delay differential equations with fixed moments and modified Ulam-Hyers-Rassias stability

Boundary Value Problems
Abstract In this paper, we discuss the existence and uniqueness of solution of Atangana-Baleanu-Caputo impulsive fractional delay differential equations with caratheo-dory function. We further introduce modified Ulam-Hyers-Rassias stability criteria by considering a real-valued function that is Lebesque integrable.

Stability in the Sense of Hyers–Ulam–Rassias for the Impulsive Volterra Equation

Fractal and Fractional
This article aims to use various fixed-point techniques to study the stability issue of the impulsive Volterra integral equation in the sense of Ulam–Hyers (sometimes known as Hyers–Ulam) and Hyers–Ulam–Rassias.
