摘要:

本文是作者最近发表的论文(Journal of数学物理55(2014)083519)的延续,其中导出了与作为时间导数的Caputo导数和作为空间导数的Riesz-Feller导数相关联的分布阶统一反应扩散方程的计算解。研究了以分数阶广义Riemann-Liouville导数为时间导数,Riesz-Feller导数为空间导数的分布阶分数阶反应扩散方程的可计算解.本文给出了分数阶反应扩散方程的解。推导解所遵循的方法是联合拉普拉斯变换和傅里叶变换。所得到的解是一个封闭的和可计算的形式在熟悉的广义Mittag-Leffler函数。它们提供了优雅的文献中给出的结果的扩展。

英文摘要:

This paper is in continuation of the authors' recently published paper (Journal of Mathematical Physics 55(2014)083519) in which computational solutions of an unified reaction-diffusion equation of distributed order associated with Caputo derivatives as the time-derivative and Riesz-Feller derivative as space derivative is derived. In the present paper, computable solutions of distributed order fractional reaction-diffusion equations associated with generalized Riemann-Liouville derivatives of fractional orders as the time-derivative and Riesz-Feller fractional derivative as the space derivative are investigated. The solutions of the fractional reaction-diffusion equations of fractional orders are obtained in this paper. The method followed in deriving the solutions is that of joint Laplace and Fourier transforms. The solutions obtained are in a closed and computable form in terms of the familiar generalized Mittag-Leffler functions. They provide elegant extensions of the results given in the literature.
