HILFER AND HADAMARD RANDOM FRACTIONAL DIFFERENTIAL EQUATIONS IN FRECHET SPACES

摘要

This paper deals with some existence and Ulam stability results for Hilfer and Hilfer-Hadamard type fractional random differential equations in Frechet spaces. A random fixed point theorem is applied to prove the existence of random solutions. Also it is shown that the solutions to our problems are generalized Ulam-Hyers-Rassias stable.
