Hadamard导数的极值原理及其在非线性分数阶偏微分方程中的应用

Extremum principle for the Hadamard derivatives and its application to nonlinear fractional partial differential equations

Mokhtar Kirane, Berikbol T. Torebek

摘要:

本文给出了函数在其极值点的Hadamard分数阶导数的新估计。然后应用极值原理证明了线性和非线性时间分数阶扩散方程的初边值问题至多存在一个经典解,且该解连续依赖于初始和边界条件.证明了具有分数阶Hadamard导数的椭圆型方程的极值原理。

英文摘要:

In this paper we obtain new estimates of the Hadamard fractional derivatives of a function at its extreme points. The extremum principle is then applied to show that the initial-boundary-value problem for linear and nonlinear time-fractional diffusion equations possesses at most one classical solution and this solution depends continuously on the initial and boundary conditions. The extremum principle for an elliptic equation with a fractional Hadamard derivative is also proved.
