摘要：In this talk, the blow-up mechanism for a class of quasilinear integrable equations which could possess peakons is investigated. The dynamics of the blow-up quantity involves interplay between the solution $u$ and its gradient $u_x$. We provide two different approaches. The first one is based on a refined analysis on either the evolution of $Cu \pm u_x$ or the growth rate of the relative ratio $u_x/u$. The second one isolates the ``truly" blowing up component from the blow-up quantity and utilizes the conservation laws to show that such a component blows up before the other component degenerates.
