 irror symmetry for log del Pezzo surfaces</a>\nby Tristan Collins (MIT) as
  part of UT Dallas Geometry-Topology Seminars\n\n\nAbstract\nIf X is a del
  Pezzo surface and D is a smooth anti-canonical divisor\, we can regard th
 e complement X\\D as a non-compact Calabi-Yau surface.  I will discuss a p
 roof of a strong form of the Strominger-Yau-Zaslow mirror symmetry conject
 ure for these non-compact surfaces.  It turns out the mirror Calabi-Yau is
  a rational elliptic surface (in particular\, it has an elliptic fibration
  onto P^1) with a singular fiber which is a chain of nodal spheres.  I wil
 l discuss how we can construct special Lagrangian fibrations on these mani
 folds\, as well as moduli of complex and symplectic structures and how hyp
 er-Kahler rotation allows us to construct an identification of these modul
 i spaces.  This is joint work with A. Jacob and Y.-S. Lin.\n

  survey of veering triangulations</a>\nby Henry Segerman (Oklahoma State) 
 as part of UT Dallas Geometry-Topology Seminars\n\n\nAbstract\nVeering tri
 angulations are combinatorial objects introduced by Agol to describe three
 -manifolds with pseudo-Anosov bundle structures. I'll describe past work w
 ith various coauthors relating veering triangulations to other structures 
 on triangulations: strict angle structures and geometric structures\, and 
 in building censuses of veering triangulations. I'll also talk about ongoi
 ng work with Saul Schleimer to extend Agol's correspondence to manifolds w
 ith pseudo-Anosov flows\, and work with Jason Manning and Saul Schleimer t
 o produce Cannon-Thurston maps from veering triangulations. These include 
 the first examples of Cannon-Thurston maps that do not come\, even virtual
 ly\, from surface subgroups.\n
