Limits of Vertex Algebras and Large N Factorization
Thomas Gemünden, Christoph A. Keller
We investigate the limit of sequences of vertex algebras. We discuss under what condition the vector space direct limit of such a sequence is again a vertex algebra. We then apply…
The Large Limit of Orbifold Vertex Operator Algebras
Thomas Gemünden, Christoph A. Keller
We investigate the large limit of permutation orbifolds of vertex operator algebras. To this end, we introduce the notion of nested oligomorphic permutation orbifolds and discu…
Non-Abelian Orbifolds of Lattice Vertex Operator Algebras
Thomas Gemünden, Christoph A. Keller
We construct orbifolds of holomorphic lattice Vertex Operator Algebras for non-Abelian finite automorphism groups . To this end, we construct twisted modules for automorphisms $…
Orbifolds of Lattice Vertex Operator Algebras at and
Thomas Gemünden, Christoph A. Keller
Motivated by the notion of extremal vertex operator algebras, we investigate cyclic orbifolds of vertex operator algebras coming from extremal even self-dual lattices in and…
