Abstract: We prove that the two dimensional NavierStokes equations possess an exponentially attracting invariant measure. This result is in fact the consequence of a more general "Harrislike" ergodic theorem applicable to many dissipative stochastic PDEs and stochastic processes with memory. A simple iterated map example is also presented to help build intuition and showcase the central ideas in a less encumbered setting. To analyze the iterated map, a general "Doeblinlike" theorem is proven. One of the main features of this paper is the novel coupling construction used to examine the ergodic theory of the nonMarkovian processes.
