Seminar on foundations in 3-manifold topology III

We study foundational topics in 3-manifold topology. This term we will focus on hyperbolic 3-manifolds.

The seminar is scheduled for Wednesdays 2-4pm in M311. More details about the organisation of the seminar taken into account the current measurements due to the coronavirus crisis will appear later here. If you are interested in participating you should email me.

We will mainly use the following literature
  • [BP] R. Benedetti, C. Petronio, "Lectures on hyperbolic Geometry", Springer textbook
  • [L] M. Lackenby, "Hyperbolic 3-manifolds", available on M. Lackenby's homepage
  • [M] B. Martelli "An Introduction to Geometric Topology", available on the arXiv
