Abstract: Aganagic-Shakirov recently propose a refined Chern-Simons theory which gives a one-parameter deformation of quantum invariants of 3-manifolds. A key ingredient is a deformation of the S-matrix acting on the quantum Hilbert space of 2-torus, which is a modification of an earlier proposal by Gukov, Iqbal, Kozcaz and Vafa. I will give an interpretation of the deformed S-matrix in terms of Hilbert schemes of points on the plane.
