[Binghamton Geometry/Topology Seminar] March 3

[Lucas Sabalka]

                  BINGHAMTON GEOMETRY/TOPOLOGY SEMINAR

Date:  Thursday, March 3, 2011
Time:  2:50-3:50pm
Place:  Library North 2205 followed by coffee/tea in the Anderson Reading
Room.

Speaker:  Tom Farrell (Binghamton)
Title:  Twisted doubles and nonpositive curvature

Abstract: Let M be a compact smooth manifold (with boundary) such that
Int(M) supports a complete (real) hyperbolic metric of finite volume. A
twisted double of M is a closed smooth manifold obtainable by glueing
together two copies of M via some self diffeomorphism of the boundary of M.
Question. Does every such twisted double support a Riemannian metric with
all sectional curvatures nonpositive. My talk will report on joint work with
C.S. Aravinda on this question.
