Implicit Fractional Differential Equation Involving $\psi$–Caputo with Boundary Conditions [PDF]

open access: yesBulletin of the Institute of Mathematics Academia Sinica NEW SERIES, 2021
This paper deals with the existence and uniqueness of solutions for boundary-value problems of the nonlinear \(\psi\)-Caputo fractional differential equations \[ \begin{aligned} ^CD^{\alpha, \psi}_{a^+}u(t) &= f(t, u(t),^CD^{\alpha, \psi}_{a^+}u(t)), \quad t\in [a, T],\\ u(T) &= \lambda u(\eta).

Terminal Value Problem for Implicit Katugampola Fractional Differential Equations in b-Metric Spaces

open access: yesJournal of Function Spaces, 2021
This manuscript deals with a class of Katugampola implicit fractional differential equations in b-metric spaces. The results are based on the α−φ-Geraghty type contraction and the fixed point theory. We express an illustrative example.

Qualitative Study on Solutions of Piecewise Nonlocal Implicit Fractional Differential Equations

open access: yesJournal of Function Spaces, 2023
In this paper, we investigate new types of nonlocal implicit problems involving piecewise Caputo fractional operators. The existence and uniqueness results are proved by using some fixed point theorems. Furthermore, we present analogous results involving piecewise Caputo-Fabrizio and Atangana–Baleanu fractional operators.
