Weight-one elements of vertex operator algebras and automorphisms of categories of generalized twisted modules
Yi-Zhi Huang, Christopher Sadowski
Given a weight-one element of a vertex operator algebra , we construct an automorphism of the category of generalized -twisted modules for automorphisms of fixing…
-Permutation Orbifolds of Virasoro Vertex Algebras
Antun Milas, Michael Penn, Christopher Sadowski
In this paper, a continuation of \cite{MPS}, we investigate the -orbifold subalgebra of , that is, we consider the -fixed point vertex subalg…
Permutation orbifolds of Virasoro vertex algebras and -algebras
Antun Milas, Michael Penn, Christopher Sadowski
We study permutation orbifolds of the -fold and -fold tensor product for the Virasoro vertex algebra of central charge . In particular, we show that for al…
Presentations of Principal Subspaces of Higher Level Standard -Modules
Corina Calinescu, Michael Penn, Christopher Sadowski
We study the principal subspaces of higher level standard -modules, extending earlier work in the level one case, by Calinescu, Lepowsky, and Milas. We prove natural pre…
Principal subspaces of twisted modules for certain lattice vertex operator algebras
Michael Penn, Christopher Sadowski, Gautam Webb
This is the third in a series of papers studying the vertex-algebraic structure of principal subspaces of twisted modules for lattice vertex operator algebras. We focus primarily o…
Combinatorial bases of principal subspaces of modules for twisted affine Lie algebras of type , , and
Marijana Butorac, Christopher Sadowski
We construct combinatorial bases of principal subspaces of standard modules of level with highest weight for the twisted affine Lie algebras of type $A_{2l-1}^{(2…
