报告摘要: The phenomenon of second harmonic resonance for capillary-gravity waves and nonlinear optics is investigated by scattering methods, which is associated with a singular differential operator. For Schwartz initial data, the direct scattering fails uniform spectral continuity, and the nonuniqueness occurs in the inverse scattering. In addition, exponential tails yield sech-tanh profiles for large-time asymptotics.
