具有任意代数非线性项的薛定谔方程的拟周期解

Quasi-periodic solutions of the Schrödinger equation with arbitrary algebraic nonlinearities

Wei-Min Wang

摘要:

给出了时间拟周期解存在性的一个几何公式。作为应用,我们证明了任意维数$d$和任意不可积代数非线性项$p$的$b$频率$b\leq d+2$的拟周期解的存在性.这反映了$d$动量、能量和$L^2$范数的守恒。在一维情形下,我们证明了具有任意$b$的拟周期解的存在性,并且对于任意$p$,解决了一个由Hamilton PDE开始的问题.

英文摘要:

We present a geometric formulation of existence of time quasi-periodic solutions. As an application, we prove the existence of quasi-periodic solutions of $b$ frequencies, $b\leq d+2$, in arbitrary dimension $d$ and for arbitrary non integrable algebraic nonlinearity $p$. This reflects the conservation of $d$ momenta, energy and $L^2$ norm. In 1d, we prove the existence of quasi-periodic solutions with arbitrary $b$ and for arbitrary $p$, solving a problem that started Hamiltonian PDE.
