一维分数阶扩散方程移动边界问题Hopf引理的推广及其在分数阶自由边界问题中的应用

A Generalization of the Hopf's Lemma for the 1-D Moving-Boundary Problem for the Fractional Diffusion Equation and its Application to a Fractional Free-Boundary Problem

Sabrina D. Roscani

摘要:

本文研究了时间分数阶扩散方程的一维移动边界问题的理论数学分析,其中时间分数阶导数$\al$ $\in (0,1)$取Caputo意义.证明了Hopf引理的一个推广,并利用这个结果证明了当考虑分数阶自由边界Stefan问题时自由边界的单调性.

英文摘要:

This paper deals with a theoretical mathematical analysis of a one-dimensional-moving-boundary problem for the time-fractional diffusion equation, where the time-fractional derivative of order $\al$ $\in (0,1)$ is taken in the Caputo's sense. A generalization of the Hopf's lemma is proved, and then this result is used to prove a monotonicity property for the free-boundary when a fractional free-boundary Stefan problem is considered.
