ULAM STABILITY FOR HILFER TYPE FRACTIONAL DIFFERENTIAL INCLUSIONS VIA THE WEAKLY PICARD OPERATORS THEORY

Considerable attention has been recently given to the existence of solutions of initial or boundary value problems for fractional differential equations and inclusions with Hilfer fractional derivative. Motivated by these results, in this paper we will present existence, data dependence and Ulam stability results for some differential inclusions with Hilfer fractional derivative. The results follow as applications of the multi-valued weakly Picard operator theory. An example illustrates the main result of the paper.
