p-Laplacian的一个反问题:边界确定

An inverse problem for the p-Laplacian: boundary determination

Mikko Salo, Xiao Zhong

摘要:

本文研究了一类非线性椭圆型方程的反问题。证明了电导率系数的边界值是由非线性Dirichlet-to-Neumann映射给出的边界测量值唯一确定的。该结果是构造性的,局部的,并给出了一种方法,用于确定系数的边界点在一个小的邻域内的测量。证明工作直接与非线性方程,而不是基于线性化。在复值的情况下,我们采用复杂的几何光学类型的解决方案的基础上的p-调和指数,而对于真正的情况下,我们使用的p-调和函数首先介绍了沃尔夫。

英文摘要:

We study an inverse problem for nonlinear elliptic equations modelled after the p-Laplacian. It is proved that the boundary values of a conductivity coefficient are uniquely determined from boundary measurements given by a nonlinear Dirichlet-to-Neumann map. The result is constructive and local, and gives a method for determining the coefficient at a boundary point from measurements in a small neighborhood. The proofs work with the nonlinear equation directly instead of being based on linearization. In the complex valued case we employ complex geometrical optics type solutions based on p-harmonic exponentials, while for the real case we use p-harmonic functions first introduced by Wolff.
