Lectures by Nathan Dunfield at the Groups around 3-manifolds workshop at CRM during June 5-9, 2023.
General background about the the topology and geometry of 3-manifolds, including the statement of the Geometrization Theorem. This lecture is intended to provide a common base of knowledge for all the mini-courses, not just this one.
Solvability of the homeomorphism problem for 3-manifolds. Practical demonstration.
Finding hyperbolic structures by solving Thurston's gluing equations.
Fun with finite-covers of 3-manifolds: A story of topology, geometry, and arithmetic. Basically, torsion growth in towers of finite covers a la Bergeron-Venkatesh, Lê, and Lück.
