Abstract. Ergodicity for a Markov process with an infinite dimensional phase-space is a delicate question. In general little is known. The 2D Navier Stokes equations can be viewed as an infinite collection of coupled diffusions. I will discuss some conditions under which we know the system has a unique invariant measure. The mechanism for this uniqueness is different in different regimes. Along our journey, we will visit compositions of random contractions, random attractors, diffusions with infinite memory, and coupling in the infinite dimensional context. ------------------------------------------------------------------------ The Department of Statistics is in Sequoia Hall, at the intersection of Serra Mall and Lomita Mall, near the Math. corner of the Main Quadrangle.
