Abstract
I plan to discuss how the old problem dealing with statistics of random walks on a multi-punctured plane, manifests, via the optimal flow in the modular domain, in the selection of Fibonacci series appearing in equilibration of long-range repulsive particles on the surface of the cylinder.
Speaker Intro
I graduated in 1985 from the Department of Physics at Moscow State University. From 1991 to 2007, I was affiliated with the Landau Institute for Theoretical Physics.
Since 2008, I have been working in France, where I currently hold the position of Director of Research at CNRS (National Center for Scientific Research, France). I am based at the LPTMS (Laboratory of Theoretical Physics and Statistical Models), a laboratory affiliated with both CNRS and the University of Paris-Saclay (https://www.lptms.universite-paris-saclay.fr/).
From 2015 to 2022, I served as the Director of the Interdisciplinary Scientific Center Poncelet, an International Research Laboratory of CNRS, located at the Independent University of Moscow (Moscow, Russia).
I have authored more than 140 scientific publications in Web of Science journals. My current scientific interests are systematized below, where the list of main publications is presented. These publications constitute the core of references related to the course “Statistics and Topology of Random Paths”.
