Decouple a coupled KdV system of Nutku and Oguz
Heng Chun Hu, Q. P. Liu
Abstract
A coupled KdV system with a free parameter proposed by Nutku and Oguz is considered. It is shown that the system passes the WTC's Painlevé test for arbitrary value of the parameter. A further analysis yields that the parameter can be scaled away and the system can be decoupled.
