Title:Telescopic actions
Seminar:Geometry Luncheon Seminar
Speaker:Anton Petrunin, PSU
Abstract:
A group action H on X is called "telescopic" if for any finitely presented group G, there exists a subgroup H' in H such that G is isomorphic to the fundamental group of X/H'. We construct few examples of telescopic actions. As an application we give an alternative proof of Taubes' theorem: "For every finitely presented group G there exists a smooth compact complex 3-manifold with fundamental group isomorphic to G." This is joint work with Dmitri Panov.
