Title:
Square function estimate for the cone in R^3

Speaker:
Hong Wang

Abstract:
We prove a sharp square function estimate for the cone in R^3 and consequently the local smoothing conjecture for the wave equation in 2+1 dimensions. The proof uses induction on scales and an incidence estimate for points and tubes. This is joint work with Larry Guth and Ruixiang Zhang.
