非线性双调和方程解的稳定性与相交性

Stability and intersection properties of solutions to the nonlinear biharmonic equation

Paschalis Karageorgis

摘要:

研究了非线性双调和方程$Δ^2 ϕ= ϕ^p$的正的、正则的、径向对称的解.首先,我们证明了存在一个临界值$p_c$,依赖于空间维数,这样的解决方案是线性不稳定的,如果$p<p_c$和线性稳定,如果$p\geq p_c$。然后,我们专注于超临界情况下$p\geq p_c$,我们表明,没有两个解决方案的图形相交。

英文摘要:

We study the positive, regular, radially symmetric solutions to the nonlinear biharmonic equation $Δ^2 ϕ= ϕ^p$. First, we show that there exists a critical value $p_c$, depending on the space dimension, such that the solutions are linearly unstable if $p<p_c$ and linearly stable if $p\geq p_c$. Then, we focus on the supercritical case $p\geq p_c$ and we show that the graphs of no two solutions intersect one another.
