Progress in Fractional Differentiation & Applications

Author Country (or Countries)



The point of this work is to analyze and investigate the suffcient conditions of the existence and uniqueness of explicit solution for ψ-Hilfer fractional differential equation (FDEs) with constant coefficient in the form of Mittag-Leffler (ML) function by using Holder inequality and two well-known fixed point theorems, namely Banach and Schaefer. Utilizing generalised Gronwall inequality lemma, Eκ -Ulam stability results is evaluated. Additionally, some examples are provided to demonstrate how our findings can be applied.
