超线性椭圆型方程的解及其Morse指数

Solutions of super-linear elliptic equations and their Morse indices

Foued Mtiri

摘要:

本文研究退化双调和方程:$$Δ_{m}^2 u=f(x,u)\; \;\;\mbox{in} Ø,\quad u = Δu = 0\quad \mbox{on }\; \pΩ,$$与$m\ge 2,$,以及退化三调和方程:$$ -Δ_{m}^3 u=f(x,u)\;\;\; \mbox{in} Ø,\quad u = \frac{\p u}{\p ν} = \frac{\p^{2} u}{\pν^{2}} = 0\quad \mbox{on }\; \pΩ,$$,其中$Ω\subset \mathbb{R}^{N}$是一个有界区域,分别具有光滑边界$N>4$或$N>6$,且$f \in \mathrm{C}^{1}(Ω\times \mathbb{R})$满足适当的m-超线性和亚临界增长条件.我们的主要目的是通过Morse指标建立弱解的$L^{p}$和$L^{\infty}$显式界。我们的结果推广了以前在\cite{c, HHF, hyf, lec}中得到的显式估计。

英文摘要:

We investigate here the degenerate bi-harmonic equation: $$Δ_{m}^2 u=f(x,u)\; \;\;\mbox{in} Ø,\quad u = Δu = 0\quad \mbox{on }\; \pΩ,$$ with $m\ge 2,$ and also the degenerate tri-harmonic equation: $$ -Δ_{m}^3 u=f(x,u)\;\;\; \mbox{in} Ø,\quad u = \frac{\p u}{\p ν} = \frac{\p^{2} u}{\pν^{2}} = 0\quad \mbox{on }\; \pΩ,$$ where $Ω\subset \mathbb{R}^{N}$ is a bounded domain with smooth boundary $N>4$ or $N>6$ resp, and $f \in \mathrm{C}^{1}(Ω\times \mathbb{R})$ satisfying suitable m-superlinear and subcritical growth conditions. Our main purpose is to establish $L^{p}$ and $L^{\infty}$ explicit bounds for weak solutions via the Morse index. Our results extend previous explicit estimate obtained in \cite{c, HHF, hyf, lec}.
