Song of the Week: Big Star - Way Out West

This song starts as if they are making up as they go along. Which in Big Star's case probably wasn't a million miles from the truth. But wait for the chorus.

Big Star did it all. Made unfashionable music at the wrong time, sold no records, self-destructed and influenced generations of subsequent bands. As they sing: "Love me, we can work out the rest".

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.
