Left-orderability in Dehn fillings of pseudo-Anosov mapping tori

Bojun Zhao

For pseudo-Anosov mapping tori with co-orientable invariant foliations and monodromies reversing their co-orientations, a family of taut foliations was constructed in previous work…

Co-orientable taut foliations in Dehn fillings of pseudo-Anosov mapping tori with co-orientation-reversing monodromy

Bojun Zhao

Let $I^£$ be a compact orientable surface with nonempty boundary, let $I ¨ : I^£ \to I^£$ be an orientation-preserving pseudo-Anosov homeomorphism, and let $M = Î£\times I / \stackrelÏ{…

Reconstruction of Anosov flows from infinity

Hyungryul Baik, Chenxi Wu, Bojun Zhao

Every pseudo-Anosov flow $I ¨ $ in a closed $3$ -manifold $M$ gives rise to an action of $I ¨ _{1} (M)$ on a circle $S_{\infty}^{1} (I ¨ )$ from infinity \cite{Fen12}, with a pair of invarian…
