Events for 17 November 2017
Given some chiral conformal field theory, a natural but highly non-
trivial task is to classify its representation theory. In this talk, I will
use some well known examples of conformal field theories, such as the Virasoro
minimal models, to show how certain hard questions in representation theory of
conformal field theories can be neatly rephrased as comparatively easy
questions in the theory of symmetric polynomials. After a brief overview of
the theory of symmetric polynomials, I will show how they can be used to
classify irreducible representations.
Oana Pocovnicu: A two-soliton with transient turbulent regime for a focusing cubic nonlinear half-wave equation on the real line
In this talk we consider a nonlocal focusing cubic half-wave equation on the real line. Evolution problems with nonlocal dispersion naturally arise in physical settings which include models for wave turbulence, continuum limits of lattice systems, and gravitational collapse. The goal of the talk is to present the construction of an asymptotic global-in-time modulated two-soliton solution of small mass, which exhibits the following two regimes: (i) a turbulent regime characterized by an explicit growth of high Sobolev norms on a finite time interval, followed by (ii) a stabilized regime in which the high Sobolev norms remain stationary large forever in time. This talk is based on joint work with P. Gerard (Orsay, France), E. Lenzmann (Basel, Switzerland), and P. Raphael (Nice, France).
