Twisted representations of vertex operator superalgebras

C Dong, Z Zhao - Communications in Contemporary Mathematics, 2006 - World Scientific
This paper gives an analogue of Ag (V) theory for a vertex operator superalgebra V and an
automorphism g of finite order. The relation between the g-twisted V-modules and Ag (V) …

Induced modules for vertex operator algebras

C Dong, Z Lin - Communications in mathematical physics, 1996 - Springer
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 ag-twisted induction functor from …

Bimodules and 𝑔-rationality of vertex operator algebras

C Dong, C Jiang - Transactions of the American Mathematical Society, 2008 - ams.org
This paper studies the twisted representations of vertex operator algebras. Let $ V $ be a
vertex operator algebra and $ g $ an automorphism of $ V $ of finite order $ T. $ For any $ m …

Associative algebras for (logarithmic) twisted modules for a vertex operator algebra

YZ Huang, J Yang - Transactions of the American Mathematical Society, 2019 - ams.org
We construct two associative algebras from a vertex operator algebra $ V $ and a general
automorphism $ g $ of $ V $. The first, called a $ g $-twisted zero-mode algebra, is a …

Generalized twisted modules associated to general automorphisms of a vertex operator algebra

YZ Huang - Communications in Mathematical Physics, 2010 - Springer
We introduce a notion of a strongly C^ *-graded, or equivalently, C/Z-graded generalized g-
twisted V-module associated to an automorphism g, not necessarily of finite order, of a …

Let $ V $ be a vertex operator algebra and $ g $ an automorphism of finite order. We
construct an associative algebra $ A_g (V) $ and a pair of functors between the category of …

Local systems of twisted vertex operators

HS Li - Moonshine, the Monster, and Related Topics: Joint …, 1996 - books.google.com
We introduce the notion of “local system of ZT-twisted vertex operators” on a Z2-graded
vector space M, generalizing the notion of local system of vertex operators [Li]. First, we …

On intertwining operators and finite automorphism groups of vertex operator algebras
