Title:
On triangulation of 3d polyhedra and sequences of monotone flips
Time & Venue:
2018.7.18 10:00am N208
Abstract:
A sequence of flips in the plane triangulation is called monotone, if every flip will cause a function strictly decrease (or increase). In this talk, I will discuss a relation between monotone flips and triangulations of 3d polyhedra. This gives a nice directed graph structure on the set of triangulations of 2d points. Some open issues will be explored.
