Virasoro action on Imaginary Verma modules and the operator form of the KZ-equation
Published 22 Dec 2011 in math.RT, math-ph, and math.MP | (1112.5361v1)
Abstract: We define the Virasoro algebra action on imaginary Verma modules for affine sl(2) and construct the analogs of Knizhnik-Zamolodchikov equation in the operator form. Both these results are based on a free field realization of imaginary Verma modules.
