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.

On some problems related to the study of random matrices

Abstract: I will make an overview of questions and problems relating to the study of random matrices with independent rows or columns. We relate this subject to questions from harmonic analysis (like the problem of selection of characters), compressed sensing or approximating the covariance matrix of a random vector. These questions naturally required to develop the study of some empirical and Gaussian processes.

Chebyshev Lab Colloquium
Thursday, 14 April, 17:00, room 14. Pavel Exner (Doppler Institute for Mathematical Physics and Applied Mathematics, Prague), "Many quantum graphs with the same geometry". Quantum graph models are both interesting mathematically and useful in applications. One of the important questions they pose concerns the meaning of the vertex coupling. The self-adjointness requirement alone leaves a substantial freedom expressed through parameters appearing in the conditions matching the wave function at the graph vertices. It is a longstanding problem whether one can motivate their choice by approximating the graph Hamiltonian by operators on a family of networks, i.e. systems of tubular manifolds the transverse size of which tends to zero. It appears that the answer depends on the conditions imposed on tube boundaries. In this talk we present a complete solution for Neumann networks: we demonstrate that adding properly scaled potentials and changing locally the graph topology, one can approximate any admissible vertex coupling. The result comes from a common work with Taksu Cheon, Olaf Post, and Ond?rej Turek.
