Integrable Combinatorics

Colloquium presented by Philippe Di Francesco (Service de Physique Théorique, CEA Saclay (France))

Borrowing examples from statistical physics, we address various enumerative and algebraic combinatorial problems, such as counting maps with marked points at fixed geodesic distances, or exploring relations between alternating sign matrices, plane partitions and the geometry of orbital varieties, via a connection to lattice loop gas. We will show how classical or quantum integrability inherited from the structure of the physical theories at hand can be used to derive exact combinatorial results.
