In this talk, I will talk about the global well-posedness and regularity for a sequence of scalar PDEs with cusp singularity. This sequence of PDEs includes important integrable system models modeling water wave, such as Camassa-Holm and Novikov equations. We will discuss the solutions in the space of H^1, to include the solutions beyond wave breaking.
