Vertex operator expressions for Lie algebras of physical states
Thomas Driscoll-Spittler
We study the Lie algebra of physical states associated with certain vertex operator algebras of central charge 24. By applying the no-ghost theorem from string theory we express th…

Reflective modular varieties and their cusps
Thomas Driscoll-Spittler, Nils R. Scheithauer, Janik Wilhelm
We classify reflective automorphic products of singular weight under certain regularity assumptions. Using obstruction theory we show that there are exactly 11 such functions. They…
