An Integral Equation Involving Legendre Functions [PDF]

open access: yes, 1964
Rodrigues’s formula can be applied also to (1.1) and (1.3) but here the situation is slightly more involved in that the integrals with respect to σ^2 are of fractional order and their inversion requires the knowledge of differentiation and integration of

Fractional Sturm-Liouville eigenvalue problems, II [PDF]

open access: yes, 2017
We continue the study of a non self-adjoint fractional three-term Sturm-Liouville boundary value problem (with a potential term) formed by the composition of a left Caputo and left-Riemann-Liouville fractional integral under {\it Dirichlet type} boundary

A fractional B-spline collocation method for the numerical solution of fractional predator-prey models [PDF]

open access: yes, 2018
We present a collocation method based on fractional B-splines for the solution of fractional differential problems. The key-idea is to use the space generated by the fractional B-splines, i.e., piecewise polynomials of noninteger degree, as approximating

Fractional order differentiation by integration with Jacobi polynomials [PDF]

open access: yes, 2012
The differentiation by integration method with Jacobi polynomials was originally introduced by Mboup, Join and Fliess. This paper generalizes this method from the integer order to the fractional order for estimating the fractional order derivatives of ...

A New Class of Fractional Cumulative Residual Entropy - Some Theoretical Results

open access: yesJournal of Telecommunications and Information Technology, 2023
In this paper, by differentiating the entropy’s generating function (i.e., h(t) = R SX̄F tX (x)dx) using a Caputo fractional-order derivative, we derive a generalized non-logarithmic fractional cumulative residual entropy (FCRE).

A comparison between numerical solutions to fractional differential equations: Adams-type predictor-corrector and multi-step generalized differential transform method [PDF]

open access: yes, 2017
In this note, two numerical methods of solving fractional differential equations (FDEs) are briefly described, namely predictor-corrector approach of Adams-Bashforth-Moulton type and multi-step generalized differential transform method (MSGDTM), and then

Chaos in fractional order financial model with fractal–fractional derivatives

open access: yesPartial Differential Equations in Applied Mathematics, 2023
Recently, a new differential operator which combines fractal differentiation and fractional differentiation with different kernels such as power law, exponential decay, and the Mittag–Leffler function has been introduced.
