Induced modules for vertex operator algebras
For a vertex operator algebra V and a vertex operator subalgebra V ′ which is invariant under an automorphism g of V of finite order, we introduce a g-twisted induction functor from the category of g-twisted V ′-modules to the category of g-twisted V -modules. This functor satisfies the Frobenius reciprocity and transitivity. The results are illustrated with V ′ being the g-invariants in simple...
متن کاملTwisted modules for vertex operator algebras
In this contribution, I explain the general principles of twisted modules for vertex operator algebras in its powerful formulation using formal series, and derive new general relations satisfied by twisted and non-twisted vertex operators. I prove new “equivalence” and “construction” theorems, identifying a very restricted set of sufficient conditions in order to have a twisted module for a ver...
متن کاملTensor Products of Modules for a Vertex Operator Algebra and Vertex Tensor Categories Yi-zhi Huang and James Lepowsky
In this paper, we present a theory of tensor products of classes of modules for a vertex operator algebra. We focus on motivating and explaining new structures and results in this theory, rather than on proofs, which are being presented in a series of papers beginning with [HL4] and [HL5]. An announcement has also appeared [HL1]. The theory is based on both the formal-calculus approach to verte...
متن کاملTensor Product of Vertex Operator Algebras
Let V =V1 ⊗ V2 be a tensor product of VOAs. Using Zhu theory we discuss the theory of representations of V (associative algebra, modules and ’fusion rules’). We prove that this theory is more or less the same as representation theory of tensor product of the associative algebras.
متن کاملOn Tensor Products of Operator Modules
The injective tensor product of normal representable bimodules over von Neumann algebras is shown to be normal. The usual Banach module projective tensor product of central representable bimodules over an Abelian C∗-algebra is shown to be representable. A normal version of the projective tensor product is introduced for central normal bimodules.
