Let M be a smooth manifold and Diff 0 (M) the group of all smooth diffeomorphisms on M with compact support. Our main subject in this paper concerns the existence of certain quasi-invariant measures on groups of diffeomorphisms, and the denseness of C . -vectors for a given unitary representation U

The convex set M a of quasi-invariant measures on a locally convex space E with given ``shift''-Radon Nikodym derivatives (i.e., cocycles) a=(a tk ) k # K 0 , t # R is analyzed. The extreme points of M a are characterized and proved to be non-empty. A specification (of lattice type) is constructed s

For a geometrically and stochastically complete, noncompact Riemannian manifold, we show that the flows on the path space generated by the Cameron-Martin vector fields exist as a set of random variables. Furthermore, if the Ricci curvature grows at most linearly, then the Wiener measure (the law of
