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…

Reconstruction of Anosov flows from infinity

Hyungryul Baik, Chenxi Wu, Bojun Zhao

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

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

Bojun Zhao

Let $Σ$ be a compact orientable surface with nonempty boundary, let $φ : Σ \to Σ$ be an orientation-preserving pseudo-Anosov homeomorphism, and let $M = Σ \times I / \sim φ$ …
