格点sine-Gordon方程的多尺度展开

Multiscale expansion of the lattice sine--Gordon equation

Xiaoda Ji, Decio Levi, Matteo Petrera

摘要:

本文将离散时间格点sine-Gordon方程展开到多重格点上,得到了支配其远场行为的偏差分方程。这样的约化使我们得到一个新的完全离散的非线性薛定谔(NLS)型方程。

英文摘要:

We expand a discrete--time lattice sine--Gordon equation on multiple lattices and obtain the partial difference equation which governs its far field behaviour. Such reduction allow us to obtain a new completely discrete nonlinear Schröedinger (NLS) type equation.
