Coupled higher-order nonlinear Schroedinger equations: a new integrable case via the singularity analysis
S. Yu. Sakovich, Takayuki Tsuchida
Abstract
A new system of coupled higher-order nonlinear Schroedinger equations is proposed which passes the Painleve test for integrability well. A Lax pair and a multi-field generalization are obtained for the new system.
