DESCRIPTION:Lattice Yang-Mills is a model of a collection of m
atrices. We consider its Langevin dynamic (stochas
tic quantization) which is a system of SDEs. Using
this SDE system\, we give a simple derivation of
the Makeenko-Migdal loop equations\, prove uniquen
ess and ergodicity\, log-Sobolev and Poincare ineq
ualities\, large N limits and exponential decay of
correlations at strong coupling. These are based
on joint works with Scott Smith\, Rongchan Zhu and
Xiangchan Zhu. The dynamics in continuum in 2D an
d 3D have been recently constructed by Chandra\, C
hevyrev\, Hairer and the speaker\, and part of the
motivation of the talk is to see if certain prope
rties of the YM model can be extracted from the dy
namics with a simplification of a lattice cutoff.
