Hyers-Ulam stability of fuzzy fractional Volterra integral equations with the kernel ψ−function via successive approximation method

In this paper, we investigative the Hyers-Ulam stability and the Hyers-Ulam-Rassias stability of fuzzy fractional Volterra integral equations (FFVIEs) involving the kernel ψ−function. We propose conditions for the existence, uniqueness, and stability of FFVIE by employing the method of successive approximation. To visualize the theoretical results, some examples and numerical simulations are given.
