$\mathbb{R}^2$中非局部变分问题解的存在性

Existence of solutions for a nonlocal variational problem in $\mathbb{R}^2$ with exponential critical growth

Claudianor O. Alves, Minbo Yang

摘要:

本文研究了一类非局部问题$$ -Δu +V(x)u =\Big( I_μ\ast F(x,u)\Big)f(x,u) \quad \mbox{in} \quad \mathbb{R}^2, $$解的存在性,其中$V$是正周期势,$I_μ=\frac{1}{|x|^μ}$,$0<μ<2$和$F(x,s)$是$f(x,s)$在变量$s$中的原函数.本文假设非线性方程$f(x,s)$在无穷远处具有指数临界增长,利用变分方法证明了解的存在性.

英文摘要:

We study the existence of solution for the following class of nonlocal problem, $$ -Δu +V(x)u =\Big( I_μ\ast F(x,u)\Big)f(x,u) \quad \mbox{in} \quad \mathbb{R}^2, $$ where $V$ is a positive periodic potential, $I_μ=\frac{1}{|x|^μ}$, $0<μ<2$ and $F(x,s)$ is the primitive function of $f(x,s)$ in the variable $s$. In this paper, by assuming that the nonlinearity $f(x,s)$ has an exponential critical growth at infinity, we prove the existence of solutions by using variational methods.
