报告摘要： We will talk about long-time asymptotics for vector mKdV equations via the nonlinear steepest descent method.
An introduction on computing asymptotics by method of stationary phase or method of steepest descent will be given.
Starting from Riemann-Hilbert problems associated vector mKdV equations, we'll make deformations of the Riemann-Hilbert problems and finally compute long-time asymptotes by the integral representation of the solutions.
