Refined Chern-Simons theory and invariants of torus knotsQMAP Seminar
|Speaker: ||Eugene Gorsky, UC Davis, Math Dept|
|Location: ||2112 MSB|
|Start time: ||Thu, Jan 28 2016, 3:10PM|
Aganagic and Shakirov proposed a deformation of the Chern-Simons theory and gave a precise
mathematical construction of the refined invariants of torus knots in terms of Macdonald polynomials.
We give a geometric interpretation of these invariants using the moduli space of instantons on R^4,
and use it to compute the invariants explicitly. The talk is based on a joint work with Andrei Negut.
