We consider the following equation
$$\begin{aligned} -\Delta u+u=Q_n(x)|u|^{p-2}u, \quad x\in {\mathbb {R}}^{N}, \end{aligned}$$where \(Q_n\) are concrete bounded functions whose self-focusing core \(\text{ supp }\, Q_n^+\) shrinks to a finite set of points as \(n\rightarrow \infty \). We investigate the limiting profile of concentration for the ground state solutions and construct localized bound state solutions of concentration type.

我们考虑以下等式
$$ \ begin {aligned}-\ Delta u + u = Q_n(x)| u | ^ {p-2} u,\ quad x \ in {\ mathbb {R}} ^ {N},\ end {aligned } $$其中\(Q_n \)是具体的有界函数,其自聚焦核心\(\ text {supp} \,Q_n ^ + \)缩小为一组有限的点,作为\(n \ rightarrow \ infty \)。我们研究了基态溶液浓度的极限分布,并构建了浓度类型的局部束缚态溶液。
