退化抛物型完全非线性方程的渐近性及其在椭圆型本征值问题中的应用

Asymptotic Behavior in Degenerate Parabolic Fully Nonlinear equations and its application to Elliptic Eigenvalue Problems

Soojung Kim, Ki-ahm Lee

摘要:

我们研究了非线性抛物流$u_{t}=F(D^2 u^m)$当$t\ra \infty$为$m\geq 1$时的渐近行为,以及下列椭圆型非线性本征值问题解的几何性质:F(D^2 \vp)&+ μ \vp^{p} =0,\quad \vp >0 \quad \text{in $Ω$} \vp &=0 \quad \text{on $\pΩ$},(严格)凸光滑域$Ω\subset\re^n$对于$0< p \leq 1,$,其中$F(\cdot)$是一致椭圆的,一阶正齐次的和凹的.我们建立了$\log (\vp)$在$p=1$情形下是凹的,函数$\vp^{\frac{1-p}{2}}$在$0<p<1.$情形下是凹的

英文摘要:

We study the asymptotic behavior of the nonlinear parabolic flows $u_{t}=F(D^2 u^m)$ when $t\ra \infty$ for $m\geq 1$, and the geometric properties for solutions of the following elliptic nonlinear eigenvalue problems: F(D^2 \vp) &+ μ\vp^{p}=0, \quad \vp>0\quad\text{in $Ω$} \vp&=0\quad\text{on $\pΩ$} posed in a (strictly) convex and smooth domain $Ω\subset\re^n$ for $0< p \leq 1,$ where $F(\cdot)$ is uniformly elliptic, positively homogeneous of order one and concave. We establish that $\log (\vp)$ is concave in the case $p=1$ and that the function $\vp^{\frac{1-p}{2}}$ is concave for $0<p<1.$
