Convergence of Fourier Series: Past, Present, Future


Abstract: One of Lennart Carleson's famous theorems states that the Fourier series of square integrable functions on the circle converge pointwise. Its method of proof requires techniques of analysis of functions in both time and frequency variables, methods which in recent years have found a range of applications to other difficult areas of harmonic analysis. This talk will survey the developments associated to Carleson's theorem, and some of the challenging questions that remain unresolved.
