Congratulations!

The Chebyshev Lab congratulates Aleksandr Logunov for the Clay Research Award!
This has led to the solution of longstanding problems in spectral geometry, for instance the optimal lower bound on the measure of the nodal set of an eigenfunction of the LaplaceBeltrami operator in a compact smooth manifold (Yau and Nadirashvili's conjectures).

Zhan Shi (Lame Chair)
"Branching random walks"
Lecture 1: Thursday 13.04, 15:25.
Branching random walks and branching Brownian motions are branching systems where each individual, also referred to as particle, is associated with a spatial parameter representing the fitness value of the individual. They are connected to FisherKolmogorovPetrovskiiPiskunov (FKPP) partial differential equations, logarithmically correlated Gaussian fields including the twodimensional Gaussian free field, Liouville Brownian motion, planar quadrangulations, Derrida's Generalized Random Energy Model (GREM) of spin glasses. I am going to give an elementary and selfcontained introduction to the study of the structure of extreme positions in branching random walks and branching Brownian motions.

Chebyshev Lab Minicourse

G. Uraltsev (Bonn University) will give a lecture course "Timefrequency 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 timefrequency analysis was introduced by Lennart Carleson in his seminal paper on the pointwise a.e. convergence of the Fourier series for $L^2$ functions. From a more general perspective, timefrequency analysis tries to put together the theory of operators defined by highly oscillatory integrals with CalderonZygmund theory of singular integral operators. We will study two prime examples of operators in timefrequency 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 CalderonZygmund operators. We will show how the theory of outer measure L^p spaces on the timefrequencyscale space of symmetries provides an efficient functional framework for dealing with the above operators.
