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.

Chebyshev Lab Course

Gabriel Lame Chair and Chebyshev Lab organize a course "Determinantal processes".

Lector: Alexander Bufetov (Universite Aix-Marseille, MIAN, ...)

Time and place: every Tuesday from 1 November to 27 December, 17:15, room 413 (14th Line 29B, Vasilyevsky Island).

Determinantal point processes naturally appear in many problems of representation theory, asymptotic combinatorics and mathematical physics, especially, the theory of random matrices. They have recently become an extremely active area of research. The course will give an elementary introduction to determinantal point processes.
