环域中的超临界椭圆方程

A supercritical elliptic equation in the annulus

Alberto Boscaggin, Francesca Colasuonno, Benedetta Noris, Tobias Weth

AI总结:

本文在环域中研究超临界椭圆方程,利用变分与拓扑方法结合不变锥,构造了新的正轴对称解,并在常数系数情形下给出解非径向的充分条件。

摘要:

通过结合变分与拓扑技术,并在不变锥存在的情况下,我们检测到环域 $A \subset \mathbb R^N$($N\ge3$)中椭圆方程 $$ -\Delta u + u = a(x)|u|^{p-2}u $$ 的 Dirichlet 问题的一类新的正轴对称解。这里 $p>2$ 允许是超临界的,且 $a(x)$ 是轴对称但可能非径向的函数,具有额外的对称性和单调性性质,这些性质也被我们构造的解 $u$ 所共享。在 $a$ 等于正常数的情况下,我们检测到仅依赖于指数 $p$ 和环域内半径的条件,这些条件确保解是非径向的。

英文摘要:

By a combination of variational and topological techniques in the presence of invariant cones, we detect a new type of positive axially symmetric solutions of the Dirichlet problem for the elliptic equation $$ -Δu + u = a(x)|u|^{p-2}u $$ in an annulus $A \subset \mathbb R^N$ ($N\ge3$). Here $p>2$ is allowed to be supercritical and $a(x)$ is an axially symmetric but possibly nonradial function with additional symmetry and monotonicity properties, which are shared by the solution $u$ we construct. In the case where $a$ equals a positive constant, we detect conditions, only depending on the exponent $p$ and on the inner radius of the annulus, that ensure that the solution is nonradial.
