Abstract

Let MM be a connected, closed, orientable, irreducible 33-manifold. We show that: if MM admits a co-orientable taut foliation F\mathcal{F} with orderable cataclysm, then π1(M)\pi_1(M) is left orderable. This provides an elementary proof that π1(M)\pi_1(M) is left orderable if MM admits an Anosov flow with a co-orientable stable foliation without using Thurston's universal circle action. Furthermore, for every closed orientable 3-manifold that admits a pseudo-Anosov flow XX with a co-orientable stable foliation, our result applies to infinitely many of Dehn fillings along the union of singular orbits of XX.
