"One cannot hear the winding number"

Abstract: We construct an example of two continuous functions from the circle to itself with identical absolute value of the Fourier coefficients, and different winding numbers, answering a question of Brezis. Joint work with Jean Bourgain.

Light refreshments will be served in the faculty lounge at 3:30.
