报告题目:Stability of dispersive shock in KdV Burgers equation
报 告 人:沈燕南,堪萨斯大学 副教授
报告摘要:We study the viscous-dispersive shock profile with infinite oscillations of the Korteweg–de Vries–Burgers (KdVB) equation. First, we establish detailed structures of the shock wave, including the rate at which the local extrema converge to the left end state towards the left far field. Then, by exploiting the structural properties of the shock, we show the L2 contraction property of the shock profile under arbitrarily large perturbations, up to a time-dependent shift. This result implies both time-asymptotic stability and uniform stability with respect to the viscosity and dispersion coefficients. This uniformity yields zero viscosity-dispersion limits.
