 T/1/">Mirror symmetry for log del Pezzo surfaces</a>\nby Tristan Collins (
 MIT) as part of UT Dallas Geometry-Topology Seminars\n\n\nAbstract\nIf X i
 s a del Pezzo surface and D is a smooth anti-canonical divisor\, we can re
 gard the complement X\\D as a non-compact Calabi-Yau surface.  I will disc
 uss a proof of a strong form of the Strominger-Yau-Zaslow mirror symmetry 
 conjecture for these non-compact surfaces.  It turns out the mirror Calabi
 -Yau is a rational elliptic surface (in particular\, it has an elliptic fi
 bration onto P^1) with a singular fiber which is a chain of nodal spheres.
   I will discuss how we can construct special Lagrangian fibrations on the
 se manifolds\, as well as moduli of complex and symplectic structures and 
 how hyper-Kahler rotation allows us to construct an identification of thes
 e moduli spaces.  This is joint work with A. Jacob and Y.-S. Lin.\n

 T/2/">A survey of veering triangulations</a>\nby Henry Segerman (Oklahoma 
 State) as part of UT Dallas Geometry-Topology Seminars\n\n\nAbstract\nVeer
 ing triangulations are combinatorial objects introduced by Agol to describ
 e three-manifolds with pseudo-Anosov bundle structures. I'll describe past
  work with various coauthors relating veering triangulations to other stru
 ctures on triangulations: strict angle structures and geometric structures
 \, and in building censuses of veering triangulations. I'll also talk abou
 t ongoing work with Saul Schleimer to extend Agol's correspondence to mani
 folds with pseudo-Anosov flows\, and work with Jason Manning and Saul Schl
 eimer to produce Cannon-Thurston maps from veering triangulations. These i
 nclude the first examples of Cannon-Thurston maps that do not come\, even 
 virtually\, from surface subgroups.\n
