• #### Tathagata Basak to speak in the Geometry/Topology Seminar on Tuesday, Dec 12 at 3pm in Eckhart 208

The title of the talk is "A complex ball quotient and the monster". Let $$B$$ be the unit ball in the standard 13-dimensional complex vector space. We shall talk about a ball quotient obtained by removing a locally finite collection of complex hyperplanes from $$B$$ and then quotienting the rest by the action of a discrete subgroup of $$U(13,1)$$. We shall state a conjecture that relates the fundamental group of this ball quotient and the monster simple group and describe our results towards this conjecture. The Leech lattice plays a central role. This is joint work with Daniel Allcock.

• #### Professor Wilkinson writes in the New York Times about Marina Ratner and Maryam Mirzakhani (Aug 14, 2017)

The mathematical world in general, and we, in particular, have suffered two great losses this year with the deaths of Marina Ratner and of Maryam Mirzakhani. Amie Wilkinson has shared some of her feelings in a moving and scientifically interesting tribute in the New York Times. The link is below.
