DESCRIPTION:I will talk about the mixing time which is the time it takes f
 or a random walk to reach equilibrium. My focus will be on the cutoff phen
 omenon observed when the transition to equilibrium happens abruptly in tim
 e. I will survey the developments in the last 30 years and present a recen
 t universality result for graphs with a random matching that was obtained 
 in collaboration with J. Hermon and A. Sly. \n\nA wine reception will be h
 eld in the Central Core following this talk.
