Abstract: Both the study of low regularity solutions and the study of the long time dynamics for quasilinear pde's are challenging fundamental questions in dispersive flows. Usually these are considered separately, but recent research shows that it is instead natural to study them together. The talk will provide an overview of several new ideas an results in this direction, ranging from water waves and nonlinear wave equation to nonlinear Schroedinger flows. This is joint work with Mihaela Ifrim, and also in part with Albert Ai.
