Topology/Geometry Seminar

Non-arithmetic lattices in PSL(2,C) are normalizers

Tamunonye Cheetham-West (Yale)

Location:  Hill 705
Date & time: Tuesday, 05 November 2024 at 4:00PM - 5:00PM

In this talk we will discuss how we can combine geodesic counting theorems in hyperbolic manifolds and theorems about controlled quotients of virtually special groups to see that every non-arithmetic lattice in PSL(2,C) is the full (orientation-preserving) automorphism group of some other lattice. This is joint work with Ian Agol and Yair Minsky.
