5D能量临界wave equation中激发多孤子的构造

Construction of excited multi-solitons for the 5D energy-critical wave equation

Xu Yuan

摘要:

对于5D能量临界波动方程,我们构造了具有共线速度的激发态$N$ -孤子,即方程的解$u$使得\begin{equation*} \lim_{t\to+\infty}\bigg\|\nabla_{t,x}u(t)-\nabla_{t,x}\bigg(\sum_{n=1}^{N}Q_{n}(t)\bigg)\bigg\|_{L^{2}}=0, \end{equation*}其中对于$n=1,\ldots,N$,$Q_n(t,x)$是非简并且充分衰减的激发态的洛伦兹变换,每个激发态具有不同但共线的速度.存在性的证明遵循Martel-Merle和Elemente-Martel关于能量临界波和非线性Klein-Gordon方程的思想。特别是,我们依赖于一个能量方法和线性化运营商的一般bavity属性。

英文摘要:

For the 5D energy-critical wave equation, we construct excited $N$-solitons with collinear speeds, i.e. solutions $u$ of the equation such that \begin{equation*} \lim_{t\to+\infty}\bigg\|\nabla_{t,x}u(t)-\nabla_{t,x}\bigg(\sum_{n=1}^{N}Q_{n}(t)\bigg)\bigg\|_{L^{2}}=0, \end{equation*} where for $n=1,\ldots,N$, $Q_n(t,x)$ is the Lorentz transform of a non-degenerate and sufficiently decaying excited state, each with different but collinear speeds. The existence proof follows the ideas of Martel-Merle and Côte-Martel developed for the energy-critical wave and nonlinear Klein-Gordon equations. In particular, we rely on an energy method and on a general coercivity property for the linearized operator.
