Representation theory and a little bit of quantum field theory
Ben Webster (Waterloo)
Abstract: One of the central foci of representation theory in the 20th century was the representation theory of Lie algebras, starting with finite dimensional algebras and expanding to a rich, but still mysterious infinite dimensional theory. In this century, we realized that this was only one special case of a bigger theory, with new sources of interesting non-commutative algebras whose representations we'd like to study, such as Cherednik algebras. In mathematical terms, we could connect these to symplectic resolutions of singularities, but a more intriguing explanation is that they arise from 3d quantum field theories. I'll try to provide an overview about what's known about this topic and what we're still confused about.
