Abstract:
The concept of sparse domination was first introduced for singular integral operators and then extended to many other operators in harmonic analysis. I will discuss a general sparse domination principle that applies to large classes of operators beyond the Calderón--Zygmund theory, but usually does not cover endpoint cases. There are several new results in this direction, covering for example classical oscillatory multipliers and Bochner-Riesz means at the critical index.
