The standard diffusion processes are known to be obtained as the limits of appropriate random walks. These prelimiting walks can quite different, however. coefficient made responsible for size jumps or intensity jumps. limit does not feel difference. situation changes if we model jump-type approximations via CTRW with non-exponential waiting times. If make and take times from domain attraction ...

Abstract In this manuscript, we examine both the existence and stability of solutions to implicit boundary value problem Caputo fractional differential equations variable order. We construct an example illustrate validity observed results.

{ Fractional calculus allows to generalize the standard (linear and one dimensional) diiusion equation by replacing the second-order space derivative by a derivative of fractional order. If this is taken as the pseudo-diierential operator introduced by Feller in 1952 the fundamental solution of the resulting diiusion equation is a probability density evolving in time and stable in the sense of ...

A finite element method formulation is developed for the solution of anomalous diffusion equation. This equation belongs to branch mathematics called fractional calculus: it governed by a partial differential in which time derivative, whose order ranges interval (0,1), replaces first-order derivative classical In this work, Caputo integro-differential operator employed represent derivative.
