On a Nonlocal Problem for Mixed-Type Equation with Partial Riemann-Liouville Fractional Derivative

open access: yesFractal and Fractional, 2022
The present paper presents a study on a problem with a fractional integro-differentiation operator in the boundary condition for an equation with a partial Riemann-Liouville fractional derivative. The unique solvability of the problem is proved.

A new Definition of Fractional Derivative and Fractional Integral [PDF]

open access: yesKirkuk Journal of Science, 2018
In this paper, we introduce three different definitions of fractional derivatives, namely Riemann-Liouville derivative, Caputo derivative and the new formula Caputo expansion formula, and some basics properties of these derivatives are discussed.

On the solution of the space-time fractional cubic nonlinear Schrödinger equation

open access: yesResults in Physics, 2018
The space–time fractional nonlinear Schrödinger equation is studied based on the modified Riemann–Liouville derivative. The fractional mapping expansion method is used to find analytical solution of this model.

A possible generalization of acoustic wave equation using the concept of perturbed derivative order [PDF]

open access: yes, 2013
The standard version of acoustic wave equation is modified using the concept of the generalized Riemann-Liouville fractional order derivative. Some properties of the generalized Riemann-Liouville fractional derivative approximation are presented.

Fractional variational iteration method and its application to fractional partial differential equation [PDF]

open access: yes, 2013
We use the fractional variational iteration method (FVIM) with modified Riemann-Liouville derivative to solve some equations in fluid mechanics and in financial models. The fractional derivatives are described in Riemann-Liouville sense.
