Résumé:
The aim of this work is to study that the existence of solution of stochastic fractional di§eren-
tial equations with LÈvy noise is established by the Picard-Lindelˆf successive approximation
scheme. The stability of nonlinear stochastic fractional dynamical system with LÈvy noise is
obtained using Mittag Le≠ er function. Examples are provided to illustrate the theory.
