|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.|
