Department of Mathematics Colloquium

Speaker: Larry Guth, MIT

Abstract: The local smoothing problem asks about how much solutions to the wave equation can focus. It was formulated by Chris Sogge in the early 90s. Hong Wang, Ruixiang Zhang, and I recently proved the conjecture in two dimensions. In the colloquium, we will build up some intuition about waves to motivate the conjecture, and then discuss some of the obstacles and some ideas from the proof.
