Understanding Tubular Groups

Presented by: 
Daniel Woodhouse McGill University
Tuesday 10th January 2017 - 11:30 to 12:30
INI Seminar Room 1
A group is tubular if it splits as a graph of groups with rank 2 free abelian vertex groups and infinite cyclic edge groups. Tubular groups have been an interesting source of counterexamples in geometric group theory. I will introduce the examples of Gersten and Wise before moving onto recent results relating to cubulating tubular groups. This will include a classification of virtually special tubular groups.
