Existence, uniqueness and matrix-valued fuzzy Mittag–Leffler–Hypergeometric–Wright stability for P-Hilfer fractional differential equations in matrix-valued fuzzy Banach space.

We introduce a new class of fuzzy control functions and define the concept of matrix-valued fuzzy Mittag–Leffler–Hypergeometric–Wright stability. Then, we apply Radu–Mihet method derived from an alternative fixed point theorem to investigate existence, uniqueness and matrix-valued fuzzy Mittag–Leffler–Hypergeometric–Wright stability of a a class of P -Hilfer fractional differential equations in matrix-valued fuzzy Banach space. Next, we show the main results for unbounded domains. An example is given to illustrate the Mittag–Leffler–Hypergeometric–Wright stability for a fractional system. [ABSTRACT FROM AUTHOR]
