摘要：in this talk, i will introduce some integrable models which possess peaked solitons (peakons), including the well-known camassa-holm (ch), the degasperis-procesi (dp), and other new peakon equations developed in recent years. i will take the ch case as a typical example to explain the details. in particular, the ch peakon equation is able to be extended to the dp, the b-family, the forq, the novikov, the modified ch (moch), and other higher order models with peakons or pseudo-peakons. some open problems will also be addressed for discussion in the end. some work is joint with baoqiang xia and enrique reyes.
