具有Trudinger-Moser临界非线性项的半线性椭圆型方程径向解的浓度分布、能量和弱极限

Concentration profile, energy, and weak limits of radial solutions to semilinear elliptic equations with Trudinger-Moser critical nonlinearities

摘要:

我们研究下一个Trudinger-Moser临界方程,\[ \begin{cases} -Δu=λue^{u^2+α|u|^β}&\text{ in }B,\\ u=0&\text{ on }\partial B, \end{cases} \]其中$α>0$,$(λ,β)\in(0,\infty)\times(0,2)$和$B\subset \mathbb{R}^2$是以原点为中心的单位球。我们对径向解的能量有界序列的渐近行为进行了分类。通过爆破分析和标度技术,我们推导出极限轮廓,能量和几个渐近公式的集中解与弱极限的精确信息。特别地,我们得到了关于集中点处弱极限振幅的一个新的必要条件。这给出了Grossi-Mancini-Naimen-Pistoia在2020年提出的径向情形下的猜想的一个证明。此外,在$β\le1$的情况下,我们表明,任何序列进行最多一个气泡。这使得一个新的证明不存在的低能量节点径向解的$(λ,β)$在适当的范围内。最后,我们讨论了我们的分类结果的几个对应。特别地,我们证明了一个带有多个气泡且弱收敛于变号解的解序列的存在性。

英文摘要:

We investigate the next Trudinger-Moser critical equations, \[ \begin{cases} -Δu=λue^{u^2+α|u|^β}&\text{ in }B,\\ u=0&\text{ on }\partial B, \end{cases} \] where $α>0$, $(λ,β)\in(0,\infty)\times(0,2)$ and $B\subset \mathbb{R}^2$ is the unit ball centered at the origin. We classify the asymptotic behavior of energy bounded sequences of radial solutions. Via the blow--up analysis and a scaling technique, we deduce the limit profile, energy, and several asymptotic formulas of concentrating solutions together with precise information of the weak limit. In particular, we obtain a new necessary condition on the amplitude of the weak limit at the concentration point. This gives a proof of the conjecture by Grossi-Mancini-Naimen-Pistoia in 2020 in the radial case. Moreover, in the case of $β\le1$, we show that any sequence carries at most one bubble. This allows a new proof of the nonexistence of low energy nodal radial solutions for $(λ,β)$ in a suitable range. Lastly, we discuss several counterparts of our classification result. Especially, we prove the existence of a sequence of solutions which carries multiple bubbles and weakly converges to a sign-changing solution.
