Doubly periodic waves of a discrete nonlinear Schrödinger system with saturable nonlinearity

Robert Conte, Kwok-wing Chow

摘要:

本文证明了两个离散的具有饱和非线性项的Ablowitz-Ladik型薛定谔方程系统存在双周期波,并导出了其长波极限。作为副产品,几个新的解决方案的椭圆型NLS型离散和连续系统提供。

英文摘要:

A system of two discrete nonlinear Schrödinger equations of the Ablowitz-Ladik type with a saturable nonlinearity is shown to admit a doubly periodic wave, whose long wave limit is also derived. As a by-product, several new solutions of the elliptic type are provided for NLS-type discrete and continuous systems.
