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

Speaker:  Tamunonye Cheetham-West

Abstract: 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.
