Chebyshev Lab Minicourse

G. Uraltsev (Bonn University) will give a lecture course "Time-frequency analysis of modulation invariant operators using outer measure spaces".

Schedule:

Wednesday 21.12, room 413, 17:30

Friday 23.12, room 413, 17:00

Abstract:

The set of tools often referred to as time-frequency analysis was introduced by Lennart Carleson in his seminal paper on the point-wise a.e. convergence of the Fourier series for $L^2$ functions. From a more general perspective, time-frequency analysis tries to put together the theory of operators defined by highly oscillatory integrals with Calderon-Zygmund theory of singular integral operators. We will study two prime examples of operators in time-frequency analysis: the Bilinear Hilbert Transform and the Maximal Carleson operator. Both these operators have an additional modulation symmetry besides the translation and scaling symmetries of Calderon-Zygmund operators. We will show how the theory of outer measure L^p spaces on the time-frequency-scale space of symmetries provides an efficient functional framework for dealing with the above operators.
