C-algebras and their applications to reflection groups and conformal field theories
Jean-Bernard Zuber
Abstract
The aim of this lecture is to present the concept of C-algebra and to illustrate its applications in two contexts: the study of reflection groups and their folding on the one hand, the structure of rational conformal field theories on the other. For simplicity the discussion is restricted to finite Coxeter groups and conformal theories with a sl(2) current algebra, but it may be extended to a larger class of groups and theories associated with sl(N).
