报告题目：Regularity of a family of 1D quasilinear wave

报告摘要：In this talk, we consider the global well-posedness of energy conservative Holder continuous weak solution to a general quasilinear wave equation. We will start from a family of equations that support unitary directional waves and explore the formation of different singularities. We will use Novikov equation  as an example to construct a Finsler type optimal transport metric, and prove that the singular solution is Lipschitz under this metric. Finally, we will extend the frame work to a general quasilinear wave equation.
