Fractional reaction-diffusion equation [PDF]
A fractional reaction-diffusion equation is derived from a continuous time random walk model when the transport is dispersive. The exit from the encounter distance, which is described by the algebraic waiting time distribution of jump motion, interferes with the reaction at the encounter distance. Therefore, the reaction term has a memory effect.

Fractional diffusion equation with new fractional operator
A new fractional operator with Rabotnov fractional exponential kernel was recently introduced in the literature. In this paper, we consider the fractional diffusion equation in the context of this new fractional operator.

Fractional Diffusion Equations [PDF]
The Riemann-Liouville fractional integrals and derivatives. There exist many definitions of fractional derivatives and integrals, which are meaningful for different classes of functions, inspired by various applications etc. See [202] for a general survey and a detailed exposition of many aspects of the fractional calculus.

Similarity Solutions to Nonlinear Diffusion/Harry Dym Fractional Equations
By using scalar similarity transformation, nonlinear model of time-fractional diffusion/Harry Dym equation is transformed to corresponding ordinary fractional differential equations, from which a travelling-wave similarity solution of time-fractional ...

Fractional chemotaxis diffusion equations [PDF]
We introduce mesoscopic and macroscopic model equations of chemotaxis with anomalous subdiffusion for modelling chemically directed transport of biological organisms in changing chemical environments with diffusion hindered by traps or macro-molecular crowding.

Semi-Fractional Diffusion Equations [PDF]
It is well known that certain fractional diffusion equations can be solved by the densities of stable L vy motions. In this paper we use the classical semigroup approach for L vy processes to define semi-fractional derivatives, which allows us to generalize this statement to semistable L vy processes.
