Further solutions of fractional reaction-diffusion equations in terms of the H-function

H. J. Haubold, A. M. Mathai, R. K. Saxena

摘要:

本文是我们早先的文章的继续,在这篇文章中,我们导出了与Caputo导数作为时间导数和Riesz-Feller分数阶导数作为空间导数相关联的统一分数阶反应扩散方程的解。本文考虑了一类以Riemann-Liouville分数阶导数为时间导数,Riesz-Feller导数为空间导数的统一反应扩散方程.该解决方案是通过应用拉普拉斯和傅立叶变换在一个紧凑的和封闭的形式的H-函数。得出的结果具有一般性,包括Kilbas等人(2006年a)、Saxena等人(2006年c)和Mathai等人(2010年)早先研究的结果。主要结果以定理的形式给出。一些有趣的特殊情况下的定理也作为推论。

英文摘要:

This paper is a continuation of our earlier paper in which we have derived the solution of an unified fractional reaction-diffusion equation associated with the Caputo derivative as the time-derivative and the Riesz-Feller fractional derivative as the space-derivative. In this paper, we consider an unified reaction-diffusion equation with Riemann-Liouville fractional derivative as the time-derivative and Riesz-Feller derivative as the space-derivative. The solution is derived by the application of the Laplace and Fourier transforms in a compact and closed form in terms of the H-function. The results derived are of general character and include the results investigated earlier by Kilbas et al. (2006a), Saxena et al. (2006c), and Mathai et al. (2010). The main result is given in the form of a theorem. A number of interesting special cases of the theorem are also given as corollaries.
