Free Field Realizations of 2D Current Algebras, Screening Currents and Primary Fields
J. L. Petersen, J. Rasmussen, M. Yu
In this paper we consider Wakimoto free field realizations of simple affine Lie algebras, a subject already much studied. We present three new sets of results. (i) Based on quantiz…
