报告摘要  Abstract

      


       We report our recent work on the long-time asymptotics of the initial-value problem for the “good” Boussinesq equation on the line. The inverse scattering transform formalism implies that the solution can be expressed in terms of the solution of a three order-matrix Riemann-Hilbert problem. The long-time asymptotic behaviors of the solution are established by performing a nonlinear steepest descent analysis of this Riemann-Hilbert problem. This is a joint work with J. Lenells and C. Charlier at KTH Royal Institute of Technology in Sweden [arXiv:2003.04789v1 [math.AP] 10 Mar. 2020].
