-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…

Permutation Orbifolds of the Heisenberg Vertex Algebra

Antun Milas, Michael Penn, Hanbo Shao

We study the -orbifold of a rank three Heisenberg vertex algebras in terms of generators and relations. By using invariant theory we prove that the orbifold algebra has a mini…

Vertex-algebraic structure of principal subspaces of the basic modules for twisted Affine Kac-Moody Lie algebras of type

Michael Penn, Christopher Sadowski

We obtain a presentation of principal subspaces of basic modules for the twisted affine Kac-Moody Lie algebras of type , and . Using this pre…
