题目:    3-manifolds and their fundamental groups

报告人:Professor  Hongbin Sun (Rutgers University)

摘要:

This short course introduces topological and geometric methods to study 3-manifolds, and in particular, fundamental groups of 3-manifolds.  We will start with introducing basic tools like decomposition of 3-manifold, Dehn's lemma and hyperbolic geometry, and first study basic examples like free groups and fundamental group of surfaces. Eventually, we will cover some recent breakthrough work by Agol and others on hyperbolic 3-manifold groups,  subgroup separability and the virtual Haken conjecture.  If time permits, some more results on 3-manifold groups and high-dim manifold groups will be mentioned.  The courses should be accessible to graduate and advanced undergraduate students who are interested in geometry and topology.
