Simultaneous universal circles
Michael P. Landry, Yair N. Minsky, Samuel J. Taylor
Let phi be a pseudo-Anosov flow on a closed oriented atoroidal 3-manifold M. We show that if F is any taut foliation almost transverse to phi, then the action of pi_1(M) on the bou…

Quadratic-time computations for pseudo-Anosov mapping classes
Dan Margalit, Balázs Strenner, Samuel J. Taylor +1
We give a quadratic-time algorithm to compute the stretch factor and the invariant measured foliations for a pseudo-Anosov element of the mapping class group. As input, the algorit…

Transverse surfaces and pseudo-Anosov flows
Michael P. Landry, Yair N. Minsky, Samuel J. Taylor
Let be a transitive pseudo-Anosov flow on an oriented, compact -manifold , possibly with toral boundary. We characterize the surfaces in that are (almost) transverse…
