文摘On the basis of the spectral analysis of the 4×4 matrix Lax pair,the initial value problem of the coherently-coupled nonlinear Schrödinger system is transformed into a 4×4 matrix Riemann–Hilbert problem.By using the nonlinear steepest decent method,the long-time asymptotics of the solution of the initial value problem for the coherently-coupled nonlinear Schrödinger system is obtained through deforming the Riemann–Hilbert problem into a solvable model one.
