非线性Klein-Gordon和Schroedinger方程的紧谱解

On solutions with compact spectrum to nonlinear Klein--Gordon and Schroedinger equations

Andrew Comech

摘要:

我们考虑了非线性Schroedinger方程和非线性Klein-Gordon方程的有限能量解,找到了非线性条件,使得标准单频孤波是唯一具有紧谱的解。我们还构造了一个三维非线性狄拉克方程的四频孤波解的例子。

英文摘要:

We consider finite energy solutions to the nonlinear Schroedinger equation and nonlinear Klein--Gordon equation and find the condition on the nonlinearity so that the standard, one-frequency solitary waves are the only solutions with compact spectrum. We also construct an example of a four-frequency solitary wave solution to the nonlinear Dirac equation in three dimensions.
