一类非局部半线性方程径向极值解的正则性

Regularity of radial extremal solutions for some non local semilinear equations

Antonio Capella, Juan Dávila, Louis Dupaigne, Yannick Sire

摘要:

研究了\begin{equation*} \left \{ \begin{aligned} (-Δ)^s u&=λf(u) \qquad {\mbox{ in $B_1 \subset \R^{n}$}} \\ u&= 0 \qquad{\mbox{ on $\partial B_1$,}}\end{aligned}\right . \end{equation*}型椭圆型方程的稳定解,其中$n\ge2$,$s \in (0,1)$,$λ\geq 0$和$f$是任意光滑正超线性函数.算子$(-Δ)^s$代表分数拉普拉斯算子,一种$2s$阶的伪微分算子。根据$λ$的值,研究了弱解$u$的存在性和正则性.

英文摘要:

We investigate stable solutions of elliptic equations of the type \begin{equation*} \left \{ \begin{aligned} (-Δ)^s u&=λf(u) \qquad {\mbox{ in $B_1 \subset \R^{n}$}} \\ u&= 0 \qquad{\mbox{ on $\partial B_1$,}}\end{aligned}\right . \end{equation*} where $n\ge2$, $s \in (0,1)$, $λ\geq 0$ and $f$ is any smooth positive superlinear function. The operator $(-Δ)^s$ stands for the fractional Laplacian, a pseudo-differential operator of order $2s$. According to the value of $λ$, we study the existence and regularity of weak solutions $u$.
