Coupled higher-order nonlinear Schroedinger equations: a new integrable case via the singularity analysis

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/79743A 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.7 pages, LaTeXExactly Solvable and Integrable SystemsMathematical PhysicsAnalysis of PDEsCoupled higher-order nonlinear Schroedinger equations: a new integrable case via the singularity analysistext
