关于具有临界Sobolev指数的哈密顿系统

On Hamiltonian systems with critical Sobolev exponents

Angelo Guimarães, Ederson Moreira dos Santos

摘要:

在Brezis和Nirenberg \cite{BrezisNirenberg1983}的经典结果的启发下,本文考虑了有界光滑区域$Ω\subset \mathbb{R}^N$上临界Lane-Emden系统的低阶扰动,其中$Ω\subset \mathbb{R}^N$.我们解决的问题,找到一个积极的解决方案的所有维度$N \geq 4$。对于临界尺寸$N=3$,我们显示了一个新的现象,没有观察到的标量问题。也就是说,在临界双曲线上有部分存在所有$1$ -齐次或亚临界超线性扰动的解,而部分没有这些扰动的解。

英文摘要:

In this paper we consider lower order perturbations of the critical Lane-Emden system posed on a bounded smooth domain $Ω\subset \mathbb{R}^N$, with $N \geq3$, inspired by the classical results of Brezis and Nirenberg \cite{BrezisNirenberg1983}. We solve the problem of finding a positive solution for all dimensions $N \geq 4$. For the critical dimension $N=3$ we show a new phenomenon, not observed for scalar problems. Namely, there are parts on the critical hyperbola where solutions exist for all $1$-homogeneous or subcritical superlinear perturbations and parts where there are no solutions for some of those perturbations.
