This is a Geometry, Algebra, and Theoretical Physics seminar, jointly run with the Theoretical Physics group. The seminar is established to encourage collaboration across departments and discuss research. Talks will be in areas of common interest and made accessible to both mathematicians and physicists. One of the featured areas of research is symplectic resolutions of singularities, a unifying theme which arise in moduli spaces of physical supersymmetric gauge theories and also in algebraic geometry and representation theory. This includes quiver varieties and Coulomb branches, symplectic leaves, and geometric representation theory.
This term seminars will take place Wednesdays at noon.
For more information about the seminars, please contact one of the organisers: Travis Schedler or Amihay Hanany.
