Abstract:

The partition function of certain N = 1 supersymmetric gauge theories on S^5 and S^4 x S^1 manifolds is put into correspondence with specific correlation functions with underlying q-Virasoro symmetry. From the q-Virasoro 3-point functions, we derive a set of reflection coefficients, which can be geometrically interpreted in terms of Harish-Chandra c-functions for quantum symmetric spaces. We then link these c-functions to the types appearing in the scattering of XXZ integrable spin chain excitations.
