Abstract:

In this talk, we will first review some facts about the spectral multipliers and Bochner-Riesz means for self-adjoint operators of elliptic type. We then employ the Doob transform and methods from Grafakos-Honzík-Seeger to derive the optimal Lp bound for the maximal function generated by Hörmander-type spectral multipliers.
