Combinatorics Tutorials The aim of this section is in the series of tutorials to educate students about main theorems of Combinatorics, included into the unwritten IMO syllabus. Interactive Graph Theory Tutorials By Chris K. Caldwell from the University of Tenessee at Martin. Permutations. As of late, permutations find their way into math olympiads more and more often. The latest example is the Balkan Mathematics Olympiad 2001 where a problem was suggested which requires knowledge of permutations. NEW Friendship Theorem. When I was a member of the Problem Selection Committee in Argentina, this problem was submitted for the IMO by one of the countries. It is a beautiful theorem but I don't think it is suitable even to be a problem N6. So I think I'd rather publish it here. Back Frontpage

Department of Pure Mathematics and Mathematical Statistics DPMMS People Dr B.J. Green Dr B.J. Green Title: College Research Fellow College: Trinity College Room: E0.15 Tel: +44 1223 766857 Personal Home Page Research Interests: I like to call my area of mathematics "arithmetic combinatorics". In practice this means that I work on a variety of questions which lie at the interface of combinatorics, number theory and analysis. I particularly enjoy using the Fourier transform to prove results which, at first sight, appear to have nothing to do with harmonic analysis. More details may be found on my personal webpage.
