非局部椭圆型方程的Liouville定理

A Liouville theorem for non local elliptic equations

Louis Dupaigne, Yannick Sire

摘要:

证明了(-Δ)^sv = f(v)\qquad {in $\R^n$,}型椭圆型方程有界稳定解$v \in C^2(\R^n)$的Liouville型定理,其中$s \in (0,1)$ {和$f$是任意非负函数}.算子$(-Δ)^s$代表分数拉普拉斯算子,符号为$|ξ|^{2s}$的伪微分算子。

英文摘要:

We prove a Liouville-type theorem for bounded stable solutions $v \in C^2(\R^n)$ of elliptic equations of the type (-Δ)^s v= f(v)\qquad {in $\R^n$,} where $s \in (0,1)$ {and $f$ is any nonnegative function}. The operator $(-Δ)^s$ stands for the fractional Laplacian, a pseudo-differential operator of symbol $|ξ|^{2s}$.
