were also studied in [47]. It was conjectured in [47] that all these elliptic operators are rigid, generalizing the famous vanishing theorem of Atiyah-Hirzebruch for the Â-genus. There were several rather interesting proofs of these Witten’s conjectures (see [46], [8], [38], [41]). The one relevant to this paper is the proof given in [38], [39] where the main idea was to use the modular invariance of affine Kac-Moody characters. Note that the fibers of the bundles

We introduce certain correlation functions (graded q–traces) associated to vertex operator algebras and superalgebras which we refer to as n–point functions. These naturally arise in the studies of representations of Lie algebras of differential operators on the circle [22]–[23], [25]. We investigate their properties and consider the corresponding graded q–traces in parallel with the passage fr...

We obtain explicit expressions for all genus one chiral n-point functions for free bosonic and lattice vertex operator algebras. We also consider the elliptic properties of these functions.

متن کاملGenera of Vertex Operator Algebras and three-dimensional Topological Quantum Field Theories
The notion of the genus of a quadratic form is generalized to vertex operator algebras. We define it as the modular braided tensor category associated to a suitable vertex operator algebra together with the central charge. Statements similar as known for quadratic forms are formulated. We further explain how extension problems for vertex operator algebras can be described in terms of the associ...
متن کاملA Jacobi identity for intertwining operator algebras
We find a Jacobi identity for intertwining operator algebras. Most of the main properties of genus-zero conformal field theories, including the main properties of vertex operator algebras, modules, intertwining operators, Verlinde algebras, and fusing and braiding matrices, are incorporated into this identity. We prove that intertwining operators for a suitable vertex operator algebra satisfy t...
متن کاملGeneralized Rationality and a “Jacobi Identity” for Intertwining Operator Algebras
We prove a generalized rationality property and a new identity that we call the “Jacobi identity” for intertwining operator algebras. Most of the main properties of genus-zero conformal field theories, including the main properties of vertex operator algebras, modules, intertwining operators, Verlinde algebras, and fusing and braiding matrices, are incorporated into this identity. Together with...
