The main focus of this conference will involve the mutually perpetuating interplay between ergodic theory, combinatorics and Diophantine analysis. Ergodic theory has its roots in statistical and celestial mechanics. In studying the long term behavior of dynamical systems, ergodic theory deals with such phenomena as recurrence and uniform distribution of orbits. Ramsey theory, a branch of combinatorics, is concerned with the phenomenon of preservation of highly organized structures under finite partitions. On the other hand, Diophantine analysis concerns itself with integer and rational solutions of systems of polynomial equations.

Ergodic Ramsey theory links these three distinct areas of mathematics together in a beautiful and intricate way. This leads to spectacular proofs of old conjectures and to the opening of new promising vistas of research.

Ergodic Ramsey Theory was initiated with H. Furstenberg's ground breaking paper in Journal d'Analyse (1977) in which he introduced an ergodic-theoretic approach to certain classes of problems in additive number theory and Ramsey theory and obtained a new proof of the celebrated Szermeredi's theorem on arithmetic progressions. Since that time the ergodic theory approach has led to strong combinatorial results most of which do not have conventional combinatorial proofs.
