Topology seminar today
by Henry Segerman 12 Apr '17

12 Apr '17

Location: MSCS 428 Date and Time: Wednesday, April 12, 2017 - 3:30pm to 4:30pm Henry Segerman (Oklahoma State University) Connectivity of the set of triangulations of a 3- or 4-manifold Abstract: This is joint work with Hyam Rubinstein. Matveev and Piergallini independently show that the set of triangulations of a three-manifold is connected under 2-3 and 3-2 Pachner moves, excepting triangulations with only one tetrahedron. We give a more direct proof of their result which (in work in progress) allows us to extend the result to triangulations of four-manifolds.
