This website is dedicated to the research group on high dimensional combinatorics hosted by the Israel Institute for Advanced studies in the Hebrew University of Jerusalem (see the research group’s page on the IIAS website).

Combinatorics in general and the theory of expander graphs in particular, have been fruitful areas of interaction of pure and applied mathematics. In recent years a “high dimensional” theory has emerged. This theory, aside from its intellectual interest, also has great potential for various applications in mathematics and computer science. This theory calls for a collaboration of experts in combinatorics, topology, geometry, group theory and computer science. We propose to organize a program that will bring together people from these areas in order to create a community of scholars who can collaborate on these new challenges.
