Event details
Traditional description of the dynamics of eigenvalues origins from the seminal paper by Dyson, who proposed stochastic description of the evolution of eigenvalues. However, one can rephrase this problem in another language, similar to the toy-model of turbulence formulated by Burgers. In this picture one can identify spectral viscosity and spectral shock waves, and determine critical exponents of the emerging universal behavior, which can be verified in lattice simulations. One can also point at several analogies to other systems, e.g. caustics phenomena in diffractive optics.
