Next meeting:
10 February	R. A. Bailey	The Levi graph and the concurrence graph

Queen Mary, University of London
School of Mathematical Sciences

Combinatorics Study Group

Notice
The School has a re-designed website. There is a CSG page on that website, here. However, the present page will continue to be maintained for the time being.

The Combinatorics Study Group meets at 4:30pm on Fridays in room M103 of the Mathematical Sciences building at Queen Mary, University of London. (Directions: Turn left on leaving Stepney Green tube station and proceed 400 metres to the building on the left.) For more information, see the directions here.

This semester's programme:

13 January: Thomas Müller, Presentations associated with group actions on sets
20 January: Peter Cameron, Small subsquares of Latin squares
27 January: Olof Sisask, Arithmetic progressions in sumsets via probability, geometry and analysis
3 February: Simeon Ball, Complete bipartite Turán numbers
10 February: R. A. Bailey, The Levi graph and the concurrence graph
17 February: No meeting
24 February: Robert Johnson, tba (tentative)
2 March: Sasha Gnedin, Block characters of the symmetric groups
9 March: Catherine Greenhill (New South Wales): Making Markov chains less lazy

In March there will probably be two talks on acyclic orientations of graphs, one by Robert Schumacher, and the other by Peter Cameron and Celia Glass. Further talks to be announced.

Slides from Geoff Whittle's Aitken lectures: Well-quasi-ordering binary matroids and Matroid representation over infinite fields
Notes from Alan Sokal's talks
List of talks since 1999 (The data from 1999 to 2005 is thanks to Robin Whitty, Robert Bailey, and Michael Giudici; it is incomplete and not quite correct. I'd be interested in hearing from anyone who has corrections, or records of earlier talks.)
Notes from some previous talks

The Combinatorics Study Group has been running since 1986. The original participants were Peter Cameron, Liam Halpenny and Mark Whelan.
