DESCRIPTION:Dr Bjoern Bringmann (IAS & Princeton University)\nWe consider
  the wave maps equation for maps from (1+1)-dimensional Minkowski space i
 nto a compact Lie group. The Gibbs measure of this model corresponds to a 
 Brownian motion on the Lie group\, which is a natural object from stochas
 tic differential geometry. Our main result is the invariance of the Gibbs
  measure under the wave maps equation and is the first result of this kin
 d for any geometric wave equation. The proof combines techniques from dif
 ferential geometry\, partial differential equations\, and probability theo
 ry.
