... conformal field theory at c = 24 (other than the Monster theory) containsstates of weight one, and therefore an affine subtheory [11]. The theory can thenbe analysed in terms of this subtheory, and using ... the meromorphic subtheory and its representa-tions, i.e. the zero- and two-point functions of the theory. In order to understand thestructure of the theory further we need to analyse next the ... Lepowsky and A. Meurman, Vertex Operator Algebras and the Monster, AcademicPress, 1988.[15] I. Frenkel, Y Z.
