分数阶Laplacian的高阶延拓

On higher order extensions for the fractional Laplacian

Ray Yang

摘要:

Caffarelli和Silvestre的技巧,将分数拉普拉斯算子刻画为满足具有一个额外空间维度的上半空间中的椭圆型方程的函数U的Dirichlet-to-Neumann映射,通过证明边界上的H^s范数与U的适当高阶范数之间的等价性,证明了分数拉普拉斯算子的一般正的非整数阶是成立的。

英文摘要:

The technique of Caffarelli and Silvestre, characterizing the fractional Laplacian as the Dirichlet-to-Neumann map for a function U satisfying an elliptic equation in the upper half space with one extra spatial dimension, is shown to hold for general positive, non-integer orders of the fractional Laplace operator, by showing an equivalence between the H^s norm on the boundary and a suitable higher-order seminorm of U.
