Coarse geometry of planar groups

Joe MacManus
Abstract

Virtually planar groups (that is, those groups with a finite-index subgroup admitting a planar Cayley graph) exhibit many fairly unique coarse geometric properties. Often, we find that any one of these properties completely characterises this class of groups. 

In this talk, I will survey some characterisations of virtually planar/virtual surface groups. Among other things, I will sketch why any group which is QI to a planar graph is necessarily virtually planar. Time permitting, I will discuss an upcoming new characterisation of virtual surface groups in terms of their coarse geometry.

Lunch with Beethoven

Are you looking for a relaxing and inspiring way to have your lunch? On Tuesday 28 January at 1pm, Castalian String Quartet will be back in Cafe π playing a free taster performance of Beethoven’s string quartet Opus 59. 

Rewley Lecture

Saïd Business School are delighted to extend an invitation to attend the annual Rewley Lecture. 

The lecture will this year be held on the 19th February in the Sheldonian Theatre.  We’ll be joined by Biz Stone (pictured), co-founder of Twitter, and Evan Sharp, co-founder of Pinterest to deliver the lecture titled ‘Reconnecting with the Sacred in a Technology-Driven World’.
