DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GPRTatNU/54/
 ">Representation theory and a little bit of quantum field theory</a>\nby B
 en Webster (Waterloo) as part of Geometry\, Physics\, and Representation T
 heory Seminar\n\n\nAbstract\nOne of the central foci of representation the
 ory in the 20th century was the representation theory of Lie algebras\, st
 arting with finite dimensional algebras and expanding to a rich\, but stil
 l mysterious infinite dimensional theory. In this century\, we realized th
 at this was only one special case of a bigger theory\, with new sources of
  interesting non-commutative algebras whose representations we'd like to s
 tudy\, such as Cherednik algebras. In mathematical terms\, we could connec
 t these to symplectic resolutions of singularities\, but a more intriguing
  explanation is that they arise from 3d quantum field theories. I'll try t
 o provide an overview about what's known about this topic and what we're s
 till confused about.\n
