報(bào)告摘要:
In this talk, we introduce some higher order models with peakons or pseudo-peakons we proposed recently. We also present new type of peakon solutions of partial differential equations, called rogue peakons provided with a non-traveling wave. Some linear and nonlinear models are taken to illustrate the rogue peakon solutions. Some open problems will be addressed for discussion in the end. Part of work is joint with Dr. Baoqiang Xia, Dr. Quansheng Liu, and Dr. Enrique Reyes et al.
