Thoughts about Anomalous Diffusion: Time-dependent Coefficients versus Memory Functions
Relations between two natural generalizations of the standard diffusion equation, one involving memory functions and the other time-dependent coefficients, are investigated. It is shown that while the two descriptions are by no means equivalent to each other, each is equivalent to a spatially nonlocal generalization of the other. Explicit prescriptions to bridge the two formalisms are provided ...
متن کاملFractional Calculus, Anomalous Diffusion, and Probability
Ideas from probability can be very useful to understand and motivate fractional calculus models for anomalous diffusion. Fractional derivatives in space are related to long particle jumps. Fractional time derivatives code particle sticking and trapping. This probabilistic point of view also leads to some interesting extensions, including vector fractional derivatives, and tempered fractional de...
متن کاملThe Role of Fractional Time-Derivative Operators on Anomalous Diffusion
The generalized diffusion equations with fractional order derivatives have shown be quite efficient to describe the diffusion in complex systems, with the advantage of producing exact expressions for the underlying diffusive properties. Recently, researchers have proposed different fractional-time operators (namely: the Caputo-Fabrizio and Atangana-Baleanu) which, differently from the well-know...
متن کاملSimultaneous Inversion for Space-Dependent Diffusion Coefficient and Source Magnitude in the Time Fractional Diffusion Equation
We deal with an inverse problem of simultaneously identifying the space-dependent diffusion coefficient and the source magnitude in the time fractional diffusion equation from viewpoint of numerics. Such simultaneous inversion problem is often of severe ill-posedness as compared with that of determining a single coefficient function. The forward problem is solved by employing an implicit finite...
متن کاملAnomalous diffusion with linear reaction dynamics: from continuous time random walks to fractional reaction-diffusion equations.
We have revisited the problem of anomalously diffusing species, modeled at the mesoscopic level using continuous time random walks, to include linear reaction dynamics. If a constant proportion of walkers are added or removed instantaneously at the start of each step then the long time asymptotic limit yields a fractional reaction-diffusion equation with a fractional order temporal derivative o...
