DESCRIPTION:James R. Lee (University of Washington)\nIf one records a Mark
 ov process converging to stationarity from an initial distribution and the
 n plays the video in reverse\, what appears is a new (time inhomogeneous) 
 Markov process that constructs the initial distribution using as little in
 formation as possible. One can leverage this entropic optimality to study 
 the behavior of the random walk\, especially at "early" times.  For some 
 problems\, this perspective appears to offer something new over semi-group
  methods.  We discuss applications to regularizing properties of classica
 l diffusion operators and to functional inequalities on finite graphs and 
 groups.  There are interesting connections to discrete analogs of no
