一类临界增长的不定变分问题解的存在性和集中现象

Existence and concentration phenomena for a class of indefinite variational problems with critical growth

Claudianor O. Alves, Geilson F. Germano

摘要:

在本文中,我们感兴趣的是证明基态解的存在性和浓度为以下一类问题$$ -Δu+V(x)u=A(εx)f(u), \quad x \in \R^{N}, \eqno{(P)_ε} $$其中$N \geq 2$,$ε>0$,$A:\R^{N}\rightarrow\R$是一个连续的函数,满足$$ 0<\inf_{x\in\R^{N}}A(x)\leq\lim_{|x|\rightarrow+\infty}A(x)<\sup_{x\in\R^{N}}A(x)=A(0),\eqno{(A)} $$ $f:\R\rightarrow\R$是一个连续的函数有临界增长,$V:\R^{N}\rightarrow\R$是一个连续的和$\Z^{N}$-周期函数有$0\notinσ(Δ+V)$。利用变分方法,证明了$ε$问题解的存在性。在此之后,我们表明,解决方案的最大点集中在$A$的最大点。

英文摘要:

In this paper we are interested to prove the existence and concentration of ground state solution for the following class of problems $$ -Δu+V(x)u=A(εx)f(u), \quad x \in \R^{N}, \eqno{(P)_ε} $$ where $N \geq 2$, $ε>0$, $A:\R^{N}\rightarrow\R$ is a continuous function that satisfies $$ 0<\inf_{x\in\R^{N}}A(x)\leq\lim_{|x|\rightarrow+\infty}A(x)<\sup_{x\in\R^{N}}A(x)=A(0),\eqno{(A)} $$ $f:\R\rightarrow\R$ is a continuous function having critical growth, $V:\R^{N}\rightarrow\R$ is a continuous and $\Z^{N}$--periodic function with $0\notinσ(Δ+V)$. By using variational methods, we prove the existence of solution for $ε$ small enough. After that, we show that the maximum points of the solutions concentrate around of a maximum point of $A$.
