On the analysis of mixed-index time fractional differential equation systems
نویسندگان
چکیده
In this paper we study the class of mixed-index time fractional differential equations in 1 which different components of the problem have different time fractional derivatives on the left hand 2 side. We prove a theorem on the solution of the linear system of equations, which collapses to the 3 well-known Mittag-Leffler solution in the case the indices are the same, and also generalises the 4 solution of the so-called linear sequential class of time fractional problems. We also investigate the 5 asymptotic stability properties of this class of problems using Laplace transforms and show how 6 Laplace transforms can be used to write solutions as linear combinations of generalised Mittag-Leffler 7 functions in some cases. Finally we illustrate our results with some numerical simulations. 8

متن کاملA distinct numerical approach for the solution of some kind of initial value problem involving nonlinear q-fractional differential equations
The fractional calculus deals with the generalization of integration and differentiation of integer order to those ones of any order. The q-fractional differential equation usually describe the physical process imposed on the time scale set Tq. In this paper, we first propose a difference formula for discretizing the fractional q-derivative of Caputo type with order and scale index . We es...

متن کاملNonlinear Cable equation, Fractional differential equation, Radial point interpolation method, Meshless local Petrov – Galerkin, Stability analysis
The cable equation is one the most fundamental mathematical models in the neuroscience, which describes the electro-diffusion of ions in denderits. New findings indicate that the standard cable equation is inadequate for describing the process of electro-diffusion of ions. So, recently, the cable model has been modified based on the theory of fractional calculus. In this paper, the two dimensio...
