Topic: Blow-up for dispersive equations

    In this seminar we will study blow-up solutions to various dispersive equations. It is a striking feature of critical and supercritical equations (the terms will be explained in the seminar) that there are solutions which blow-up in finite time. Blow-up of an analytic solution is related to a break down of the mathematical model. We will be interested in sufficient criteria on initial data for blow-up, as well as in a precise description of the blow-up.
