[Mdtop] Today in Seminar

Hello everyone,

Today we have Bus speaking at 3:30 in MSCS 514 (not the usual room).

Title:Efficient Triangulations of 3-manifolds Abstract: We will define and discuss efficient triangulations of 3-manifolds and show that efficient triangulations of cusped 3-manifolds lift to efficient triangulations for any inflation. In particular, if a triangulation of a cusped 3-manifold is 1-efficient, then any inflation of that triangulation is 1–efficient. These results will be used in Birch’s talk on December 3.
