Title: On a scaling limit for a tagged particle in some zero-range interacting systems
Speaker: Dr. Sunder Sethuraman, Iowa State University
Date: 29 June 2007
Time: 3.00 p.m.
Venue: Lecture Hall - I, Dept. of Mathematics

Informally, the zero-range'' particle system follows a collection of dependent random walks on a lattice, each of which interacts infinitesimally only with those particles already present at its location. In this talk, we consider the asymptotics of a distinguished, or tagged particle in this interacting particle system. In particular, we discuss anonequilibrium’’ invariance principle, in one dimension when the transition rates are mean-zero, with respect to a diffusion whose coefficients depend on the ``hydrodynamic’’ density.
