Character relations and replication identities in 2d Conformal Field Theory
arXiv:1603.05511 · doi:10.1007/JHEP10(2016)020
Abstract
We study replication identities satisfied by conformal characters of a 2D CFT, providing a natural framework for a physics interpretation of the famous Hauptmodul property of Monstrous Moonshine, and illustrate the underlying ideas in simple cases.
