Entropy Production Rate of a One-Dimensional Alpha-Fractional Diffusion Process

open access: yesAxioms, 2016
In this paper, the one-dimensional α-fractional diffusion equation is revisited. This equation is a particular case of the time- and space-fractional diffusion equation with the quotient of the orders of the time- and space-fractional derivatives equal ...

On a Fractional Master Equation and a Fractional Diffusion Equation [PDF]

open access: yesMathematics and Statistics, 2013
In this paper , we derive the solutions of fractional master equation defined by (2.1) and fractional diffusion equation defined by (3.3). The method followed in deriving the solution is that of Laplace and Fourier transforms. The solutions are obtained in a neat and compact forms in terms of the generalized Mittag -Leffler function and Fox' H-function.
