Bus Jaco will speak on "Bounds for the genus of a normal surface and applications to minimal triangulations" at 3:30pm in MSCS 422. Abstract: We will show a sharp bound on the genus of a normal surface in a triangulated compact 3-manifold in terms of its normal quadrilaterals. We apply this to determining the complexity of certain infinite families of compact 3-manifolds. On Wed, Oct 22, 2014 at 1:46 PM, Henry Segerman <segerman@math.okstate.edu> wrote:

Bus Jaco will speak on "Inflations of ideal triangulations" at 3:30pm in MSCS 422.

Abstract:

We will demonstrate the construction of inflations of an ideal triangulation of the interior of a compact three manifold via examples. Several applications of inflations to constructions of efficient triangulations and Dehn fillings will be given.
