Abstract
This paper is concerned with the Ulam-Hyers and the generalized Ulam-Hyers-Rassias stability results for linear fractional differential equations with hybrid proportional-Caputo derivatives in framwork of the Laplace transform method. The existence and uniqueness of solutions for nonlinear fractional differential equations with hybrid proportional-Caputo derivatives are established by means of Schaefer’s fixed point theorem, Banach’s fixed point theorem, and generalized Gronwall’s inequality. Two examples are proposed to illustrate the main results.
