Pure Maths Colloquium: From the Klein quartic to complex hyperbolic lattices
15 October 2018 16:00 in CM221
I will review some properties of the famous Klein quartic and its automorphism group, and sketch how it can be used to give an alternative construction of the lattices in PU(2,1) obtained by the author in joint work with John Parker and Julien Paupert. Most of these lattices turn out to be non-arithmetic.
