Local smoothing for the wave equation

Colloquium presented by Larry Guth (MIT)

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.
