[Tam Nguyen Phan]

   BINGHAMTON GEOMETRY/TOPOLOGY SEMINAR


   Date: Thursday, October 16, 2014

   Time:  2.50 pm

   Place: Old Whitney Hall, Room 100E,  followed by coffee/tea in the
      Hilton Reading Room. Note the new location of the math department.


   Speaker: Andrew Nicol (Otterbein University)
   Title: Quasi-isometries of graph manifolds do not preserve non-positive
curvature

Abstract:
In this talk, we will see the definition of high dimensional graph manifold
and see that there are infinitely many examples coming from all dimensions
3 and higher of pairs graph manifolds with quasi-isometric fundamental
groups, but where one supports a locally CAT(0) metric while the other
cannot. We will use properties of the Euler class as well as various
results on bounded cohomology.
