We show that if M is a hyperbolic 3–manifold which admits a quasigeodesic flow, then π 1 (M) acts faithfully on a universal circle by homeomorphisms, and preserves a pair of invariant laminations of this circle. As a corollary, we show that the Thurston norm can be characterized by quasigeodesic flows, thereby generalizing a theorem of Mosher, and we give… CONTINUE READING
