BRST-resolution for Principally Graded Wakimoto module of {\hat sl_2}
arXiv:math/0101226
Abstract
BRST-resolution is studied for the principally graded Wakimoto module of {\hat sl_2} recently found in math.QA/0005203. The submodule structure is completely determined and irreducible representations can be obtained as the zero-th cohomology group.
