DESCRIPTION:Title: Reconstruction of Anosov flows from infinity.\n\nAbstrac
 t: The orbit space of a pseudo-Anosov flow is a topological 2-plane with a
  pair of transverse (possibly singular) foliations\, associated with a wel
 l-defined ideal circle introduced by Fenley. Bi-foliated planes were intro
 duced by Barthelmé-Frankel-Mann for describing the orbit spaces of pseudo-
 Anosov flows\, and more recently\, Barthelmé-Bonatti-Mann gave a sufficien
 t and necessary condition for reconstructing a bi-foliated plane from its 
 infinity data. From certain circle actions with infinity data\, we reconst
 ruct flows and manifolds realizing these actions\, including all orientabl
 e transitive pseudo-Anosov flows in closed 3-manifolds. This gives a geome
 tric model for such flows and manifolds\, applies to a special case of Can
 non’s conjecture and gives a description for certain hyperbolic 3-manifold
 s in terms of the distinct (ordered) triple of the ideal 2-sphere. This wo
 rk is joint with Hyungryul Baik and Chenxi Wu. A similar result was proved
  independently by Barthelmé-Fenley-Mann.\n\nWe will gather for our weekly 
 seminar teatime right after the talk.\n
