Demian Goos, Gabriela Reyero, Sabrina Roscani, Eduardo Santillan Marcus

摘要:

考虑到一些Wright函数的渐近性态以及Mainardi函数和Wright函数$W(-x,\fracα{2}, 1)$在$\mathbb{R}^+$中的界的存在性,求解了四分之一平面上时间分数阶扩散方程的三个不同的初边值问题,其中时间分数阶导数取为$α$ $\in (0,1)$的Caputo意义.此外,$α\nearrow 1$的各自的解决方案进行了分析时的限制,恢复$α=1$和分数扩散方程成为热方程时的经典边值问题的各自的解决方案。

英文摘要:

Taking into account the asymptotic behavior of some Wright functions and the existence of bounds for the Mainardi and the Wright function $W(-x,\fracα{2}, 1)$ in $\mathbb{R}^+$ , three different initial-boundary-value problems for the time-fractional diffusion equation in the quarter plane, where the time-fractional derivative is taken in the Caputo sense of order $α$ $\in (0,1)$ are solved. Moreover, the limit when $α\nearrow 1$ of the respective solutions are analyzed, recovering the respective solutions of the classical boundary-value problems when $α=1$ and the fractional diffusion equation becomes the heat equation.
