This page hosts information on Yizhi Sun's talk "What is … a Carleson operator?" at the "What is …?" seminar. The talk will take place on Friday, January 31, 1:15pm at the BMS Loft at Urania. This talk will help you better understand the talk by Lillian Pierce, which will start at 2pm.
We recall some fundamental facts about Fourier Series and different types of convergence. Then we will see how the Carleson operator and its boundedness work in the proof of Lusin's Conjecture for functions.
