本文研究了大频率数下半线性问题解的存在性和多重性$$\begin{aligned} -\varDelta u -k^2 u=Q(x)|u|^{p-2}u\quad \text { in }\mathbb {R}^N, \quad N\ge 2. \end{aligned}$$指数是次临界的,系数是连续的,非负的,满足条件$$\begin{aligned} \limsup _{|x|\rightarrow \infty }Q(x)<\sup _{x\in \mathbb {R}^N}Q(x). \end{aligned}$$在极限下,一个对偶方程的与基态相关的解序列在重新标度后,集中在函数q的全局最大值处。
This paper studies for large frequency numberthe existence and multiplicity of solutions of the semilinear problem $$\begin{aligned} -\varDelta u -k^2 u=Q(x)|u|^{p-2}u\quad \text { in }\mathbb {R}^N, \quad N\ge 2. \end{aligned}$$The exponentpis subcritical, and the coefficientQis continuous, nonnegative and satisfies the condition $$\begin{aligned} \limsup _{|x|\rightarrow \infty }Q(x)<\sup _{x\in \mathbb {R}^N}Q(x). \end{aligned}$$In the limit, sequences of solutions associated with ground states of a dual equation are shown to concentrate, after rescaling, at global maximum points of the functionQ.
