4维极值解的有界性

Boundedness of the extremal solutions in dimension 4

Salvador Villegas

摘要:

本文利用Dirichlet数据$u|_{\partial Ω}=0$建立了半线性椭圆型方程$-Δu=λf(u)$在R^N的一般光滑有界区域Omega中N=4维极值解u^* 的有界性,其中f是[0,\infty)中的C^1正非减凸函数,使得$f(s)/s\rightarrow\infty$为$s\rightarrow\infty$ .此外,我们还证明了当N>=5时,极值解$u^*\in W^{2,\frac{N}{N-2}}$ .如果N>=5,则得到$u^\ast\in L^\frac{N}{N-4}$,如果N=6,则得到$u^*\in H_0^1$。

英文摘要:

In this paper we establish the boundedness of the extremal solution u^* in dimension N=4 of the semilinear elliptic equation $-Δu=λf(u)$, in a general smooth bounded domain Omega of R^N, with Dirichlet data $u|_{\partial Ω}=0$, where f is a C^1 positive, nondecreasing and convex function in [0,\infty) such that $f(s)/s\rightarrow\infty$ as $s\rightarrow\infty$. In addition, we prove that, for N>=5, the extremal solution $u^*\in W^{2,\frac{N}{N-2}}$. This gives $u^\ast\in L^\frac{N}{N-4}$, if N>=5 and $u^*\in H_0^1$, if N=6.
