Intermittent distribution of tracers advected by a compressible random flow
Jeremie Bec, Krzysztof Gawedzki, Peter Horvai
Multifractal properties of a tracer density passively advected by a compressible random velocity field are characterized. A relationship is established between the statistical prop…
Lagrangian dispersion in Gaussian self-similar ensembles
Marta Chaves, Krzysztof Gawedzki, Peter Horvai +2
We analyze the Lagrangian flow in a family of simple Gaussian scale-invariant velocity ensembles that exhibit both spatial roughness and temporal correlations. We show that the beh…
Soluble models of turbulent advection
Krzysztof Gawedzki
Introductory lectures on the Kraichnan model of passive advection
Boundary G/G theory and topological Poisson-Lie sigma model
Fernando Falceto, Krzysztof Gawedzki
We study a boundary version of the gauged WZW model with a Poisson-Lie group G as the target. The Poisson-Lie structure of G is used to define the Wess-Zumino term of the action on…
Easy turbulence
Krzysztof Gawedzki
This is an introductory course on fully developed turbulence. It discusses: in Lecture 1: the Navier Stokes equations, existence of solutions, statistical description, energy balan…
Conformal field theory: a case study
Krzysztof Gawedzki
This is a set of introductory lecture notes devoted to the Wess-Zumino-Witten model of two-dimensional conformal field theory. We review the construction of the exact solution of t…
