# Discrete Spherical Averages

Presented by:
Michael Lacey Georgia Institute of Technology
Date:
Monday 25th February 2019 - 15:00 to 16:00
Venue:
INI Seminar Room 1
Abstract:
The strongest inequalities concerning continuous spherical averages are phrased in the language of $L^p$ improving inequalities.  Replace the  continuous averages by discrete averages, that is average over lattice points on a sphere. These inequalities then engage the continuous versions, the Hardy-Littlewood circle method, and Kloosterman sums. We will report on progress understanding these inequalities. Joint work with Robert Kesler, and Dario Mena.
