Abstracts:
Jakob Blaavand (Oxford): An integrable system from doubly periodic instantons
Abstract: We will construct an algebraically completely integrable Hamiltonian system in the moduli space of doubly periodic instantons, by finding a Lagrangian fibration in the moduli space, where the base space is the space of spectral curves associated to holomorphic bundles, and the generic fibre is the Jacobian of the spectral curve in question.
Alexandru Chirvasitu (Berkeley): Free unitary groups and free fusion rings
Abstract: Compact quantum groups (cqgs) are generalizations, in the spirit of non-commutative geometry, of compact groups, and free unitary groups are for cqgs what unitary groups are for ordinary compact groups. I will explain how they are simple (once you mod out a center).
More generally, it turns out that cqgs whose Grothendieck (or fusion) rings of representations are "free" in a certain sense are always almost simple as above. This provides an easy way to show that known families of cqgs (e.g. hyperoctahedral ones, in addition to the free unitary groups mentiond before) are simple.
