椭圆型方程解的峰值

The peak of the solution of elliptic equations

Janpou Nee

摘要:

给出了Dirichlet边值问题和J.Rauch提出的热点问题的正解区域凸性遗传的一个反例.这两个问题的难点在于解的临界点不是单点,而是一条水平曲线。然而,局部地使用Pohozeav恒等式,可以导出这两个问题的部分答案。

英文摘要:

A counter example of inheritance of convexity of domain of positive solution of Dirichlet boundary value problem and the hot spot problem that proposed by J. Rauch is given. The difficulty of these two problems is that the critical points of the solutions is not singleton but a level curve. However, using Pohozeav identity locally, partial answer to both problems can be derived.
