Our science, art and technology festival IF Oxford returns this autumn with an incredible range of exciting events and activities for everyone to connect with science and ideas up close. Most events at the Festival require pre-booking and use Pay What You Decide (PWYD) ticketing. The Festival runs throughout October and November at different venues across the city.

Zariski closures of linear reflection groups
Sami Douba
(IHES)
Abstract
We show that linear reflection groups in the sense of Vinberg are often Zariski dense in PGL(n). Among the applications are examples of low-dimensional closed hyperbolic manifolds whose fundamental groups virtually embed as Zariski-dense subgroups of SL(n,Z), as well as some one-ended Zariski-dense subgroups of SL(n,Z) that are finitely generated but infinitely presented, for all sufficiently large n. This is joint work with Jacques Audibert, Gye-Seon Lee, and Ludovic Marquis.

Unstable cohomology of SL(n,Z) and Hopf algebras
Peter Patzt
(University of Oklahoma)
Abstract
I want to give a survey about the rational cohomology of SL_n
Z. This includes recent developments of finding Hopf algebras in the
direct sum of all cohomology groups of SL_n Z for all n. I will give a
quick overview about Hopf algebras and what this structure implies for
the cohomology of SL_n Z.
