Ramsey properties of the Erdős–Renyi graph and random sets of integers

Uli Wagner (IST Austria, Austria)
Elimination of multiple intersections, and the topological Tverberg conjecture

Venue: Peston Lecture Theatre, The Graduate Centre, QMUL (please note: this is a different venue to that used in 2016; building "18" on the map)

Venue: Sheikh Zayed Theatre, New Academic Building, LSE (please note: this is a different venue to that used in 2016; building "NAB" on the map)

Contact: Julia Böttcher (j.boettcher@lse.ac.uk) and Jozef Skokan (j.skokan@lse.ac.uk)

2017 sees the eleventh year of the Colloquia in Combinatorics: each year, we present a dozen talks covering a wide range of topics of interest to all those working in combinatorics or related fields.

Those interested are welcome to attend for all or any part of the event. The two hosting institutions are less than half an hour apart by tube; it is hoped that many people will be able to attend for both days.  There is no formal registration process and seats will be allocated each day on a first come, first served basis.

Queries should be sent to Rebecca Lumb.


To view the full event programme, including schedule, please click here  You can download this PDF file, for ease of use.


Some funds are available to contribute to the basic travel expenses of UK-based research students who wish to attend the meetings.  We would ask you to keep costs to a minimum, using public transport on all occasions and off-peak student travel tariffs wherever possible.  Receipts for all journeys must be maintained as proof of travel.  At this stage, we are unable to confirm the maximum amount available; please contact Rebecca Lumb for further information.

There are also some funds available from the London Mathematical Society for help with childcare costs. Further details can be found at http://www.lms.ac.uk/content/childcare-supplementary-grants.

Event Support

Support for this event by the London Mathematical Society and the British Combinatorial Committee is gratefully acknowledged by the organisers.
