We consider a fractional differential equation of order α, α∈(2, 3], involving a ψ-Caputo
fractional derivative subject to initial conditions on function and its first derivative and an …

The idea of symmetry is a built-in feature of the metric function. In this paper, we investigate
the existence and uniqueness of a fixed point of certain contraction via orthogonal triangular …

A novel fixed-point theorem based on the degree of nondensifiability (DND) is used in this
article to examine the existence of solutions to a boundary value problem containing the ψ …

In this article, we investigate the existence, uniqueness, and different kinds of Ulam–Hyers
stability of solutions of an impulsive coupled system of fractional differential equations by …

In this paper, we study a coupled system of Hilfer type sequential fractional differential
equations supplemented with Riemann–Stieltjes integral multistrip boundary conditions. The …

This paper discusses the existence of solution for integro-differential equations via resolvent
operators in Banach space. Our approach is based on a new fixed point theorem with …
