This is a collaborative seminar, now in its eighth year, and funded by grants from the London and Edinburgh Mathematical Societies and the Glasgow Mathematical Journal. It involves geometric group theorists from Heriot-Watt, Glasgow, Newcastle, Durham, York, Leeds, Manchester, Nottingham and Leicester, and meets three times a year. On the 30th November 2011 we will meet in Newcastle, at the School of Mathematics and Statistics.
Schedule
All lectures will take place in LT3, on the ground floor of the Herschel Building (see the travel section on the left hand side) from around 1:30pm onwards.
12:00noon Lunch and Arrivals
- Informal lunch in Courtyard Restaurant on campus (Old Library Building, facing Merz Court, former home of the School of Mathematics and Statistics).
1:30pm Ric Wade (Oxford)
- Actions of lattices on right-angled Artin groups: "Automorphisms of right-angled Artin groups interpolate between $Out(F_n)$ and $GL_n(\mathbb{Z})$. An active area of current research is to extend properties that hold for both the above groups to $Out(A_\Gamma)$ for a general RAAG. After a short survey on the state of the art, we will describe our recent contribution to this program: a study of how higher-rank lattices can act on RAAGs that builds on the work of Margulis in the free abelian case, and of Bridson and the author in the free group case."
2:30pm Montse Casals-Ruiz (Oxford)
- Groups acting on real cubings: "In this talk, we will introduce the notion of a real cubing which is,in some sense, a higher-dimensional generalisation of the notion of a real tree. We will then present an analogue of the Rips' machine and establish the structure of groups acting nicely on real cubings."
3.30pm Tea/Coffee.
4.00pm Yago Antolin (Southampton)
- Big and Small subgroups of graph products: "I will discuss the structure of subgroups of graph products. The objective of the talk is to present different types of Tits alternatives for graph products of groups. This is a joint work with Ashot Minasyan."
There will be an early evening meal (around 6pm) in Newcastle, for all who are able to stay. Please let us know by Monday 28th November if you wish to come to the meal: email Nathan Barker.
Funding
We have some funds from the London and Edinburgh Mathematical Societies and the Glasgow Mathematical Journal for any participants travel costs and also for additional childcare costs incurred as a result of attending the seminar.
