Ole Brevig: Idempotent Fourier multipliers acting contractively on Lp and Hp

C*-algebra seminar talk by Ole Brevig (University of Oslo)

Title: Idempotent Fourier multipliers acting contractively on Lp and Hp

Abstract: We describe the idempotent Fourier multipliers on the d-dimensional torus Td which act contractively on Lp and Hp. This topic constitutes a part of a larger program designed to look systematically at contractive inequalities for Hardy spaces in one and several variables, and is perhaps our only true success story (so far). The presentation is based on joint work with Joaquim Ortega-Cerdà and Kristian Seip.
