带强迫项的超临界标量场方程

A supercritical scalar field equation with a forcing term

Kazuhiro Ishige, Shinya Okabe, Tokushi Sato

摘要:

研究了一类带强迫项\begin{equation} \tag{P}-Δu+u=u^p+ κμ\quad \mbox{in} \quad{\bf R}^N, \quad u>0 \quad \mbox{in} \quad {\bf R}^N, \quad u(x)\to 0\quad \mbox{as} \quad |x| \to \infty, \end{equation}的标量场方程的椭圆问题,其中$N\ge 2$,$p>1$,$κ>0$和$μ$是${\bf R}^N$中的Radon测度,且具有紧支集.在$μ$上适当的可积性条件下,给出了问题P的可解性的一个完全分类,即问题P的可解性是由$1<p<p_{JL}$给出的.这里$p_{JL}$是由$$ p_{JL} :=\infty\quad\mbox{if}\quad N\le 10, \qquad p_{JL}:=\frac{(N-2)^2-4N+8\sqrt{N-1}}{(N-2)(N-10)}\quad \text{if} \quad N\ge 11. $$定义的约瑟夫-伦德格伦指数

英文摘要:

This paper is concerned with the elliptic problem for a scalar field equation with a forcing term \begin{equation} \tag{P}-Δu+u=u^p+ κμ\quad \mbox{in} \quad{\bf R}^N, \quad u>0 \quad \mbox{in} \quad {\bf R}^N, \quad u(x)\to 0\quad \mbox{as} \quad |x| \to \infty, \end{equation} where $N\ge 2$, $p>1$, $κ>0$ and $μ$ is a Radon measure in ${\bf R}^N$ with a compact support. Under a suitable integrability condition on $μ$, we give a complete classification of the solvability of problem~(P) with $1<p<p_{JL}$. Here $p_{JL}$ is the Joseph-Lundgren exponent defined by $$ p_{JL} :=\infty\quad\mbox{if}\quad N\le 10, \qquad p_{JL}:=\frac{(N-2)^2-4N+8\sqrt{N-1}}{(N-2)(N-10)}\quad \text{if} \quad N\ge 11. $$
