Existence and Hyers–Ulam Stability for a Multi-Term Fractional Differential Equation with Infinite Delay.

This paper is devoted to investigating one type of nonlinear two-term fractional order delayed differential equations involving Caputo fractional derivatives. The Leray–Schauder alternative fixed-point theorem and Banach contraction principle are applied to analyze the existence and uniqueness of solutions to the problem with infinite delay. Additionally, the Hyers–Ulam stability of fractional differential equations is considered for the delay conditions. [ABSTRACT FROM AUTHOR]
