Fast Evaluation of the Caputo Fractional Derivative and Its Applications to Fractional Diffusion Equations

Abstract. We present an efficient algorithm for the evaluation of the Caputo fractional derivative C0D α t f(t) of order α ∈ (0, 1), which can be expressed as a convolution of f (t) with the kernel t. The algorithm is based on an efficient sum-of-exponentials approximation for the kernel t on the interval [∆t, T ] with a uniform absolute error ε, where the number of exponentials Nexp needed is ...

From Newton’s Equation to Fractional Diffusion and Wave Equations

Fractional calculus represents a natural instrument to model nonlocal or long-range dependence phenomena either in space or time. The processes that involve different space and time scales appear in a wide range of contexts, from physics and chemistry to biology and engineering. In many of these problems, the dynamics of the system can be formulated in terms of fractional differential equations...

Initial Value/boundary Value Problems for Fractional Diffusion-wave Equations and Applications to Some Inverse Problems

We consider initial value/boundary value problems for fractional diffusion-wave equation: ∂ α t u(x, t) = Lu(x, t), where 0 < α ≤ 2, where L is a symmetric uniformly elliptic operator with t-independent smooth coefficients. First we establish the unique existence of ths weak solutions and the asymptotic behaviour as the time t goes to ∞ and the proofs are based on the eigenfunction expansions. ...

Fractional Calculus of the Generalized Wright Function

The paper is devoted to the study of the fractional calculus of the generalized Wright function pΨq(z) defined for z ∈ C, complex ai, bj ∈ C and real αi, βj ∈ R (i = 1, 2, · · · p; j = 1, 2, · · · , q) by the series

Applications of He’s Variational Principle method and the Kudryashov method to nonlinear time-fractional differential equations

  In this paper, we establish exact solutions for the time-fractional Klein-Gordon equation, and the time-fractional Hirota-Satsuma coupled KdV system. The He’s semi-inverse and the Kudryashov methods are used to construct exact solutions of these equations. We apply He’s semi-inverse method to establish a variational theory for the time-fractional Klein-Gordon equation, and the time-fractiona...
