ON THE STABILITY OF DIFFERENTIAL SYSTEMS INVOLVING ψ-HILFER FRACTIONAL DERIVATIVE

This paper deals with the stability of solutions to ψ-Hilfer fractional differential systems. We derive the fundamental solution for the system by using the generalized Laplace transform and the Mittag-Leffler function with two parameters. In addition, we obtained some necessary conditions on the stability of the solutions to linear fractional differential systems for homogeneous, non-homogeneous and non-autonomous cases. Numerical examples are also given to illustrate the behavior of solutions.
