物理意义非线性方程的可积非局部渐近约化

Integrable nonlocal asymptotic reductions of physically significant nonlinear equations

Mark J. Ablowitz, Ziad H. Musslimani

摘要:

准单色复杂的减少了一些物理上重要的方程。本文从三次非线性Klein-Gordon(NLKG)、Korteweg-deVries(KdV)和水波方程出发,证明了首阶渐近逼近可以转化为与二阶(空间)非线性波方程相关的著名的可积AKNS系统[6]。这反过来又建立了,第一次,最近发现的非局部可积减少的AKNS系统和物理上有趣的方程之间的重要物理联系。约化包括宇称-时间、逆时空和逆时间非定域非线性薛定谔方程。

英文摘要:

Quasi-monochromatic complex reductions of a number of physically important equations are obtained. Starting from the cubic nonlinear Klein-Gordon (NLKG), the Korteweg-deVries (KdV) and water wave equations, it is shown that the leading order asymptotic approximation can be transformed to the well-known integrable AKNS system [6] associated with second order (in space) nonlinear wave equations. This in turn establishes, for the first time, an important physical connection between the recently discovered nonlocal integrable reductions of the AKNS system and physically interesting equations. Reductions include the parity-time, reverse space-time and reverse time nonlocal nonlinear Schrodinger equations.
