Solvability and Ulam–Hyers–Rassias stability for generalized sequential quantum fractional pantograph equations

Partial Differential Equations in Applied Mathematics
In the present manuscript, we discuss the existence, uniqueness an Ulam-stability of solutions for sequential fractional pantograph equations involving n Caputo and one Riemann–Liouville q−fractional derivatives. We prove the uniqueness of solutions for the given problem by using Banach’s contraction mapping principle.

A Fixed Point Problem for a Hybrid Contraction and Ulam–Hyers–Rassias Stability Result with Respect to w-Distance

Vestnik St. Petersburg University, Mathematics
In the present research, we consider a fixed point problem pertaining to a hybrid multivalued contractive mapping constructed by putting together the ideas behind the two well known families of contractions known as Geraghty and Kannan type contractions respectively.

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.
