The Virasoro Algebra and Some Exceptional Lie and Finite Groups

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We describe a number of relationships between properties of the vacuum Verma module of a Virasoro algebra and the automorphism group of certain vertex operator algebras.

Investigating 9d/8d non-supersymmetric branes and theories from supersymmetric heterotic strings

open access: yesJournal of High Energy Physics
We consider heterotic string theories in nine and eight dimensions. We identify the disconnected part of the spacetime gauge group by studying the outer automorphism of the charge lattices.
