In this paper we study the semiclassical nonlinear Schrödinger equation
$$\begin{aligned} -\varepsilon ^2\Delta v+V(x)v=f(v),\quad x\in {\mathbb {R}}^N. \end{aligned}$$where \(V\in C^1({\mathbb {R}}^N)\) is bounded and bounded away from zero and f is odd in v, subcritical and satisfies a monotonicity condition. We combine the del Pino and Felmer’s penalization approach and the Nehari manifold approach developed in Szulkin and Weth (J Funct Anal 257, 3802–3822, 2009; Handbook of nonconvex analysis and applications, International Press, Boston, pp 597–632, 2010) to obtain multiple localized solutions concentrating at the set of critical points of V(x).

半经典非线性Schrödinger方程的高拓扑类型的多重解
在本文中,我们研究了半经典非线性Schrödinger方程
$$ \ begin {aligned}-\ varepsilon ^ 2 \ Delta v + V(x)v = f(v),\ quad x \ in {\ mathbb {R}} ^ N。\ end {aligned} $$其中\(V \ in C ^ 1({\ mathbb {R}} ^ N)\)是有界且有界的,并且远离零,并且f在v中是奇数,亚临界且满足单调性条件。我们将del Pino和Felmer的罚分方法与在Szulkin和Weth中开发的Nehari流形方法相结合(J Funct Anal 257,3802–3822,2009;非凸分析和应用手册,国际出版社,波士顿,pp 597–632,2010)以获得集中在V(x)临界点集合上的多个局部解。
