This week, on Wednesday 16 and Thursday 17 May, there are two one-day combinatorics colloquia. The Wednesday colloquium is at Queen Mary, commencing at 10:30, and will feature talks by Julia Boettcher, Gregory Gutin, Daniel Král, Richard Mycroft, Lutz Warnke, and Günter Ziegler. The Thursday colloquium is at LSE, and the speakers are Rosemary Bailey, Magnus Bordewich, Artur Czumaj, Nikolaos Fountoulakis, János Pach, and Mathias Schacht. See the webpage here for further details, including abstracts of the talks.
The colloquia began when Anthony Hilton, who had run a one-day colloquium at Reading for many years, moved to Queen Mary, and wanted to bring the colloquium with him. At the same time, Norman Biggs retired from LSE, and his colleagues decided to take advantage of the absence of the Reading colloquium to put on an event to mark the occasion. We agreed to cooperate, and the two colloquia have continued since then.
All are very welcome!
