Character Identities Between Affine and Virasoro Vertex Operator Algebra Modules

Dražen Adamović, Dražen Adamović, Sven Möller +1

The affine vertex operator algebras for and the Virasoro minimal models are related by Drinfeld-Sokolov reduction and by the Goddard-Kent-Olive coset construction…

Modular -Crossed Tambara-Yamagami-like Categories for Even Groups

César Galindo, César Galindo, Simon Lentner +2

We explicitly construct nondegenerate braided -crossed tensor categories of the form . They are -…

Systematic Orbifold Constructions of Schellekens' Vertex Operator Algebras from Niemeier Lattices

Gerald Höhn, Gerald Höhn, Sven Möller +1

We present a systematic, rigorous construction of all 70 strongly rational, holomorphic vertex operator algebras of central charge 24 with non-zero weight-one space as cy…

Equivalence Relations on Vertex Operator Algebras, II: Witt Equivalence and Orbifolds

Sven Möller, Brandon C. Rayhaun

When can two strongly rational vertex operator algebras or 1+1d rational conformal field theories (RCFTs) be related by topological manipulations? For vertex operator algebras, the…

Computing -Crossed Extensions and Orbifolds of Vertex Operator Algebras

César Galindo, Simon Lentner, Sven Möller

In this article, we develop tools for computing -crossed extensions of braided tensor categories. Their equivariantisations appear as categories of modules of fixed-point subalg…
