Abelianization of the BGG resolution of representations of the Virasoro algebra
- 156 Downloads
We construct a resolution that permits computing the t-character of representations of the Virasoro algebra from the (2, 2p + 1)-models, i.e., the characters of the associated graded spaces with respect to the Poincaré-Birkhoff-Witt filtration.
