Pseudoprocesses governed by higher-order fractional differential equations

چکیده
We study here a heat-type differential equation of order n greater than two, in the case where the time-derivative is supposed to be fractional. The corresponding solution can be described as the transition function of a pseudoprocess Ψn (coinciding with the one governed by the standard, non-fractional, equation) with a time argument Tα which is itself random. The distribution of Tα is presented together with some features of the solution (such as analytic expressions for its moments).

Cascade of Fractional Differential Equations and Generalized Mittag-Leffler Stability
This paper address a new vision for the generalized Mittag-Leffler stability of the fractional differential equations. We mainly focus on a new method, consisting of decomposing a given fractional differential equation into a cascade of many sub-fractional differential equations. And we propose a procedure for analyzing the generalized Mittag-Leffler stability for the given fractional different...

متن کاملA Numerical Method for Solving Fuzzy Differential Equations With Fractional Order
In this paper we present a numerical method for fuzzy differential equation of fractional order under gH-fractional Caputo differentiability. The main idea of this method is to approximate the solution of fuzzy fractional differential equation (FFDE) by an implicit method as corrector and explicit method as predictor. This method is tested on numerical examples.
