哈密顿椭圆系统:变分框架指南

Hamiltonian elliptic systems: a guide to variational frameworks

Denis Bonheure, Ederson Moreira dos Santos, Hugo Tavares

摘要:

考虑\[ -Δu=H_{v}(u,v),\ -Δv=H_{u}(u,v) \ \ \text{ in } Ω, \qquad u,v=0 \text{ on } \partial Ω\]型哈密顿系统,其中$H$是幂型非线性,例如$H(u,v)= |u|^p/p+|v|^q/q$,具有亚临界增长,$Ω$是$\mathbb{R}^N$,$N\geq 1$的有界域。本文的目的是给出一个概述的几个变分框架,可以用来处理这样一个系统。在每种方法中,我们解决的解决方案,特别是基态的解决方案的存在。一些可用的框架是更充分地获得某些定性性质,我们说明了这在本调查的后半部分,在那里我们还审查了一些最新的文献主要涉及对称性,浓度和多重性的结果。本文包含了一些原始结果以及对已知事实的新的证明和方法。

英文摘要:

Consider a Hamiltonian system of type \[ -Δu=H_{v}(u,v),\ -Δv=H_{u}(u,v) \ \ \text{ in } Ω, \qquad u,v=0 \text{ on } \partial Ω\] where $H$ is a power-type nonlinearity, for instance $H(u,v)= |u|^p/p+|v|^q/q$, having subcritical growth, and $Ω$ is a bounded domain of $\mathbb{R}^N$, $N\geq 1$. The aim of this paper is to give an overview of the several variational frameworks that can be used to treat such a system. Within each approach, we address existence of solutions, and in particular of ground state solutions. Some of the available frameworks are more adequate to derive certain qualitative properties; we illustrate this in the second half of this survey, where we also review some of the most recent literature dealing mainly with symmetry, concentration, and multiplicity results. This paper contains some original results as well as new proofs and approaches to known facts.
