超临界情形下固体环面上的指数椭圆型边值问题

Exponential elliptic boundary value problems on a solid torus in the critical of supercritical case

Athanase Cotsiolis, Nikos Labropoulos

摘要:

本文研究了定义在$\mathbb{R}^3$的实心环面$\bar{T}$上的非线性指数椭圆模型问题,当数据在群$G=O(2)\times I \subset O(3)$下不变时,正解和非径向对称解的存在性.模型问题的兴趣如下所述:${ll} {\bf(P_1)} & \displaystyle Δ\upsilon+γ=f(x)e^\upsilon, \upsilon>0\quad \mathrm{on} \quad T, \quad\upsilon |_{_{\partial T}}=0.$和${ll}\bf{(P_2)} & \displaystyle Δ\upsilon+a+fe^\upsilon=0, \upsilon>0\quad \mathrm{on}\quad T, [1.3ex] &\displaystyle \frac{\partial \upsilon}{\partial n}+b+ge^\upsilon=0\quad \mathrm{on} \quad{\partial T}.$我们证明存在的解决方案是$G-$不变,这些表现出没有径向对称性。为了解决上述问题,我们需要在例外情况下找到Sobolev不等式中的最佳常数。

英文摘要:

In this paper we investigate the behavior and the existence of positive and non-radially symmetric solutions to nonlinear exponential elliptic model problems defined on a solid torus $\bar{T}$ of $\mathbb{R}^3$, when data are invariant under the group $G=O(2)\times I \subset O(3)$. The model problems of interest are stated below: ${ll} {\bf(P_1)} & \displaystyle Δ\upsilon+γ=f(x)e^\upsilon, \upsilon>0\quad \mathrm{on} \quad T, \quad\upsilon |_{_{\partial T}}=0.$ and ${ll}\bf{(P_2)} & \displaystyle Δ\upsilon+a+fe^\upsilon=0, \upsilon>0\quad \mathrm{on}\quad T, [1.3ex] &\displaystyle \frac{\partial \upsilon}{\partial n}+b+ge^\upsilon=0\quad \mathrm{on} \quad{\partial T}.$ We prove that exist solutions which are $G-$invariant and these exhibit no radial symmetries. In order to solve the above problems we need to find the best constants in the Sobolev inequalities in the exceptional case.
