Résumé:
In this work, we are concerned with a two dimension frac-
tional Lane Emden differential system with right hand side
depending on an unknown vector function. Using Banach con-
traction principle on an appropriate product Banach space, we
establish some results on the existence and uniqueness of solu-
tions. The existence of at least one solution of the considered
problem is also studied. Some notions of Ulam type stabili-
ties are presented and illustrated. At the end, an example is
discussed.
