Results on Implicit Fractional Pantograph Equations with Mittag-Leffler Kernel and Nonlocal Condition

Abstract

In this study, the main focus is on an investigation of the sufficient conditions of existence and uniqueness of solution for two-classess of nonlinear implicit fractional pantograph equations with nonlocal conditions via Atangana-Baleanu-Riemann-Liouville (ABR) and Atangana-Baleanu-Caputo (ABC) fractional derivative with order sigma is an element of 1,2. We introduce the properties of solutions as well as stability results for the proposed problem without using the semigroup property. In the beginning, we convert the given problems into equivalent fractional integral equations. Then, by employing some fixed-point theorems such as Krasnoselskii and Banach's techniques, we examine the existence and uniqueness of solutions to proposed problems. Moreover, by using techniques of nonlinear functional analysis, we analyze Ulam-Hyers (UH) and generalized Ulam-Hyers (GUH) stability results. As an application, we provide some examples to illustrate the validity of our results.
