次临界Sobolev增长的$Δu + u^p = 0$非负整体解的精化方法

A refined approach for non-negative entire solutions of $Δu + u^p = 0$ with subcritical Sobolev growth

John Villavert

摘要:

设$N\geq 2$和$1 < p < (N+2)/(N-2)_{+}$。考虑$\mathbb{R}^N$中的Lane-Emden方程$Δu + u^p = 0$,并回忆经典的Liouville型定理:如果$u$是Lane-Emden方程的非负经典解,则$u \equiv 0$。结合开尔文变换的移动平面的方法提供了这个定理的一个优雅的证明。Serrin和H.最初用于莱恩-埃姆登系统的Zou给出了另一个证明,但仅限于较低维度。受此启发,我们进一步完善这种方法,以找到一个替代证明的刘维尔型定理在所有维度。

英文摘要:

Let $N\geq 2$ and $1 < p < (N+2)/(N-2)_{+}$. Consider the Lane-Emden equation $Δu + u^p = 0$ in $\mathbb{R}^N$ and recall the classical Liouville type theorem: if $u$ is a non-negative classical solution of the Lane-Emden equation, then $u \equiv 0$. The method of moving planes combined with the Kelvin transform provides an elegant proof of this theorem. A classical approach of J. Serrin and H. Zou, originally used for the Lane-Emden system, yields another proof but only in lower dimensions. Motivated by this, we further refine this approach to find an alternative proof of the Liouville type theorem in all dimensions.
