Analysis Seminar - Applying random methods to harmonic analysis – basic ideas and some examples

Cheng Chu, Department of Mathematics, Washington University in St. Louis

September 24, 2012 - 4:00 pm to 5:00 pm
Location: Cupples I, Room 199 | Host: Prof. John McCarthy

Abstract: It is often the case in harmonic analysis that it is difficult to find a mathematical object with some prescribed properties, but it is pretty easy to exhibit a random object which enjoys the desired properties almost surely. We will begin the talk with a study of random trigonometric series and discuss the conditions for convergence and regularity. We will then show an interesting result of Kahane having to do with Lipschitz classes and convolution.
