$\mathbb{R}^N$中一类四阶椭圆型方程解的集中性

Concentration of solutions for a fourth order elliptic equation in $\mathbb{R}^N$

Liu Zhongyuan

摘要:

本文研究了四阶椭圆型方程$$ Δ^2 u=(1+εK(x)) u^{2^*-1}, \quad x\in \mathbb{R}^N $$,其中$2^*=\frac{2N}{N-4}$,$N\geq5$,$ ε>0$ .证明了当$ε$足够小时,若$K(x)$有两个满足一定条件的临界点,则上述问题存在双峰解.

英文摘要:

In this paper, we study the following fourth order elliptic problem $$ Δ^2 u=(1+εK(x)) u^{2^*-1}, \quad x\in \mathbb{R}^N $$ where $2^*=\frac{2N}{N-4}$,$N\geq5$, $ ε>0$. We prove that the existence of two peaks solutions for the above problem, if $K(x)$ has two critical points satisfying certain conditions, provided $ε$ is small enough.
