Numerical approach of riemann-liouville fractional derivative operator

open access: yesInternational Journal of Electrical and Computer Engineering (IJECE), 2021
This article introduces some new straightforward and yet powerful formulas in the form of series solutions together with their residual errors for approximating the Riemann-Liouville fractional derivative operator. These formulas are derived by utilizing

The Nehari manifold for a boundary value problem involving Riemann–Liouville fractional derivative [PDF]

open access: goldAdvances in Differential Equations, 2018
We aim to investigate the following nonlinear boundary value problems of fractional differential equations: (Pλ){−tD1α(|0Dtα(u(t))|p−20Dtαu(t))=f(t,u(t))+λg(t)|u(t)|q−2u(t)(t∈(0,1)),u(0)=u(1)=0, $$\begin{aligned} (\mathrm{P}_{\lambda}) \left ...

On the k-Riemann-Liouville Fractional Derivative

open access: yesInternational Journal of Contemporary Mathematical Sciences, 2013
The aim of this paper is to introduce an alternative denition for the k-Riemann-Liouville fractional derivative given in [6] and whose advantage is that it is the left inverse of the corresponding of k-RiemannLiouville fractional integral operator introduced by [5].

Generalized Riemann - Liouville fractional derivatives for multifractal sets

open access: green, 2000
The Riemann-Liouville fractional integrals and derivatives are generalized for cases when fractional exponent $d$ are functions of space and times coordinates (i.e. $d=d({\bf r}(t),t)$).

On q-fractional derivatives of Riemann--Liouville and Caputo type

open access: green, 2009
Based on the fractional $q$-integral with the parametric lower limit of integration, we define fractional $q$-derivative of Riemann-Liouville and Caputo type. The properties are studied separately as well as relations between them. Also, we discuss properties of compositions of these operators.
