Another spin-off of the Noga-poster-formula-competition is a MathOverflow question: Important formulas in combinatorics. The question collects important formulas representing major progress in combinatorics. So far there are 31 formulas and quite a few were new to me. There are several areas … Continue reading
Here is one of the central and oldest problems in combinatorics: Problem: Can you find a collection S of q-subsets from an n-element set X set so that every r-subset of X is included in precisely λ sets in the collection? … Continue reading
Jerusalem Combinatorics ’93 is the title of a conference I organized that took place fifteen years ago in May 9-17, 1993 at the Hebrew University of Jerusalem. It was a conference that was devoted to all areas of combinatorics. The other … Continue reading
1. About: My name is Gil Kalai and I am a mathematician working mainly in the field of Combinatorics. Within combinatorics, I work mainly on geometric combinatorics and the study of convex polytopes and related objects, and on the analysis of Boolean functions … Continue reading
