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.
