RésumeAn overdamped « rubber band » constrained to remain on a manifold evolves by trying to shorten its length, eventually settling on a closed geodesic, or collapsing entirely. It is natural to try to consider a noisy version of such a model where each infinitesimal segment of the band gets pulled in independent random directions. Trying to build such a model turns out to be surprisingly difficult and generates a number of beautiful algebraic and analytical objects. We will survey some of the main results obtained on the way to this construction
