Long-time asymptotics for the Kundu-Eckhaus equation on the half-line

The long-time asymptotics of theKundu-Eckhaus equation on the half-line are studied in the present paper. Based on a nonlinear steepest descent analysis of the associated Riemann-Hilbert problem, we can give the precise asymptotic formulas for the solution of the Kundu-Eckhaus equation on the half-line.
