具有非常数Dirichlet和Neumann数据的超定边值问题

Overdetermined boundary problems with nonconstant Dirichlet and Neumann data

Miguel Domínguez-Vázquez, Alberto Enciso, Daniel Peralta-Salas

摘要:

本文考虑$\mathbf{R}^n$中有界区域上的一般二阶半线性椭圆型方程的超定边值问题,其中解的Dirichlet和Neumann数据都是已知的.我们感兴趣的情况下,数据不一定是常数,方程的系数可以依赖于位置,所以超定问题一般不承认径向解决方案。我们的主要结果是,尽管如此,在未成年人的技术假设,非平凡的解决方案,超定边界问题总是存在的。

英文摘要:

In this paper we consider the overdetermined boundary problem for a general second order semilinear elliptic equation on bounded domains of $\mathbf{R}^n$, where one prescribes both the Dirichlet and Neumann data of the solution. We are interested in the case where the data are not necessarily constant and where the coefficients of the equation can depend on the position, so that the overdetermined problem does not generally admit a radial solution. Our main result is that, nevertheless, under minor technical hypotheses nontrivial solutions to the overdetermined boundary problem always exist.
