On the ψ -Hilfer fractional derivative

open access: yesCommunications in Nonlinear Science and Numerical Simulation, 2018
In this paper we introduce a new fractional derivative with respect to another function the so-called $\psi$-Hilfer fractional derivative. We discuss some properties and important results of the fractional calculus. In this sense, we present some uniformly convergent sequence of function results and examples involving the Mittag-Leffler function with ...

Finite-time stability of nonlinear stochastic ψ-Hilfer fractional systems with time delay

open access: yesAIMS Mathematics, 2022
In this paper, we study the finite time stability of stochastic ψ-Hilfer fractional-order time-delay systems. Under the stochastic analysis techniques and the generalized Gronwall's inequality for ψ-fractional derivative, the criterion of finite time ...

The k-fractional Hilfer derivative

open access: yesInternational Journal of Mathematical Analysis, 2013
In this paper we study a k-version of the fractional derivative of two parameter introduced by Hilfer in [4], we calculate its Laplace transform and calculate the derivative of some functions. Also study a new operator that contains in its kernel the k-Mittag-Leffler function introduced by authors in [3].
