Abstract

In this paper we study the existence of bound states for the following class of quasilinear problems, $$\begin{aligned} \left\{ \begin{aligned}&-\varepsilon ^p\Delta _pu+V(x)u^{p-1}=f(u)+u^{p^*-1},\ u>0,\ \text {in}\ {\mathbb {R}}^{N},\\&\lim _{|x|\rightarrow \infty }u(x) = 0, \end{aligned} \right. \end{aligned}$$ where \(\varepsilon >0\) is small, \(1<p<N,\) f is a nonlinearity with general subcritical growth in the Sobolev sense, \(p^{*} = pN/(N-p)\) and V is a continuous nonnegative potential. By introducing a new set of hypotheses, our analysis includes the critical frequency case which allows the potential V to not be necessarily bounded below away from zero. We also study the regularity and behavior of positive solutions as \(|x|\rightarrow \infty \) or \(\varepsilon \rightarrow 0,\) proving that they are uniformly bounded and concentrate around suitable points of \({\mathbb {R}}^N,\) that may include local minima of V.

涉及临界增长和频率的准线性椭圆问题约束状态的存在性
Abstract 在本文中,我们研究了以下一类准线性问题的约束状态的存在性: $$\begin{aligned}\left\{ \begin{aligned}&-\varepsilon ^p\Delta _pu+V(x)u^{p-1}=f(u)+u^{p^*-1},\ u>0,\text {in}\ {\mathbb {R}}^{N},\&\lim _{|x|\rightarrow \infty }u(x) = 0, \end{aligned}.\right.\end{aligned}$$ 其中 \(\varepsilon >0\) 是小的, \(1<p<N,\) f 是在索博列夫意义上具有一般次临界增长的非线性, \(p^{*} = pN/(N-p)\) 和 V 是连续的非负势。通过引入一组新的假设,我们的分析包含了临界频率情况,它允许势 V 不一定在远离零的下方有界。我们还研究了作为 \(|x|\rightarrow \infty \) 或 \(\varepsilon \rightarrow 0,\)的正解的正则性和行为,证明它们是均匀有界的、集中在 \({\mathbb {R}}^N,\) 的合适点周围,可能包括 V 的局部极小值。
