This three day workshop will bring together young (mainly postdoctoral and graduate student) researchers in representation theory and related fields with a focus on exciting new developments in algebraic and geometric methods. The meeting will incorporate both a graduate student workshop and a research level conference. The workshop component will consist of a series of three lectures by Ben Webster (Northeastern) explaining S-duality. In addition to these lectures, there will be research talks given by the leading young researchers in representation theory and related fields.

The goals of this workshop are:

  • to highlight algebraic-geometric and categorical methods in representation theory which have made important contributions in recent years,
  • to learn about the program on S-duality initiated by Braden, Licata, Proudfoot, and Webster,
  • to provide an opportunity for young researchers in the field to learn of and present cutting-edge research, and
  • to foster interaction between Canadian and American researchers working in this area.

    Speakers (speaker abstracts)

    Sabin Cautis (Columbia University)
    Ben Cooper (University of Virginia)
    Ben Elias (MIT)
    David Hill (Virginia)
    David Jordan (UT Austin)

    Jaimie Thind (Toronto)
    Ben Webster (Northeastern)

Structure of the workshop and Program

Approximately 12 talks, each 50 minutes in length, spread out over Monday, Tuesday and Wednesday, with ample time in between talks for discussion. Three of these talks will be reserved for Ben Webster’s lectures.
