三维五次wave equation的阈值现象

Threshold phenomenon for the quintic wave equation in three dimensions

Joachim Krieger, Kenji Nakanishi, Wilhelm Schlag

摘要:

对于径向情况下$\R^{3+1}$上的临界聚焦波方程$\Box u = u^5$,我们建立了在\cite{KS}中构造的“中心稳定”流形$Σ$在基态$(W,0)$附近作为I型爆破和散射到零之间的阈值的作用,建立了一个可以追溯到Bizoirs,Chmaj,Tabor数值工作的猜想。底层拓扑比能量范数更强。

英文摘要:

For the critical focusing wave equation $\Box u = u^5$ on $\R^{3+1}$ in the radial case, we establish the role of the "center stable" manifold $Σ$ constructed in \cite{KS} near the ground state $(W,0)$ as a threshold between type I blowup and scattering to zero, establishing a conjecture going back to numerical work by Bizoń, Chmaj, Tabor. The underlying topology is stronger than the energy norm.
