Harish-Chandra Modules of the Intermediate Series over the Topological N=2 Superconformal Algebra

摘要

The topological N = 2 superconformal algebra was introduced by Dijkgraaf, Verlinde and Verlinde as the symmetry algebra of topological strings at d < 1. We give a classification of irreducible Z x Z-graded modules of the intermediate series over this infinite-dimensional Lie superalgebra.
