Twisted Modules and Co-invariants for Commutative Vertex Algebras of Jet Schemes
Let Z ⊂ Ak be an affine scheme over C and J Z its jet scheme. It is well-known that C[J Z], the coordinate ring of J Z, has the structure of a commutative vertex algebra. This paper develops the orbifold theory for C[J Z]. A finite-order linear automorphism g of Z acts by vertex algebra automorphisms on C[J Z]. We show that C[J gZ], where J gZ is the scheme of g–twisted jets has the structure o...
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 کاملTwisted modules for vertex algebras associated with vertex algebroids
We continue with [LY] to construct and classify graded simple twisted modules for the N-graded vertex algebras constructed by Gorbounov, Malikov and Schechtman from vertex algebroids. Meanwhile we determine the full automorphism groups of those N-graded vertex algebras in terms of the automorphism groups of the corresponding vertex algebroids.
متن کاملTwisted Modules over Lattice Vertex Algebras
A vertex algebra is essentially the same as a chiral algebra in conformal field theory [2, 10]. Vertex algebras arose naturally in the representation theory of infinite-dimensional Lie algebras and in the construction of the “moonshine module” for the Monster finite simple group [3, 9]. If V is a vertex algebra and Γ is a finite group of automorphisms of V , the subalgebra V Γ of Γ-invariant el...
متن کاملTwisted modules for vertex operator algebras and Bernoulli polynomials
Using general principles of the theory of vertex operator algebras and their twisted modules, we obtain a bosonic, twisted construction of a certain central extension of a Lie algebra of differential operators on the circle, for an arbitrary twisting automorphism. The construction involves the Bernoulli polynomials in a fundamental way. This is explained through results in the general theory of...
