Determination of Fusion Rule for E7-Type Conformal Field Theory
We show that the fusion rule for a modular invariant Ertype conformal field theory, which is constructed from the one for the A,(l) Kac-Moody algebra by naive extension, is not associative. Then by imposing .further restrictions to this naive fusion rule, we obtain associative fusion rules for the E7-type conformal field theory. Unlike the case of an E6-type conformal field theory, these fusion...
متن کاملFusion Rules in Conformal Field Theory
Several aspects of fusion rings and fusion rule algebras, and of their manifestations in two-dimensional (conformal) field theory, are described: diagonalization and the connection with modular invariance; the presentation in terms of quotients of polynomial rings; fusion graphs; various strategies that allow for a partial classification; and the role of the fusion rules in the conformal bootst...
متن کاملBoundary Conformal Field Theory and Fusion Ring Representations
To an RCFT corresponds two combinatorial structures: the 1-loop partition function of a closed string (the amplitude of a torus, sometimes called a modular invariant), and the 1-loop partition function of an open string (a representation of the fusion ring called a NIM-rep or equivalently a fusion graph). In this paper we develop some basic theory of NIM-reps, obtain several new NIM-rep classif...
متن کاملOperads and Conformal Field Theory Lecture 1: Conformal Field Theory
Physicists have developed very advanced methods to compute such integrals. For example, the famous Feynman diagram technique allows us to compute the above integral for a rather particular function S(x), a small perturbation of a positive de nite quadratic form in R . Sometimes, elaborate techniques of physicists to compute simple things nd an amazing application to very general things in mathe...
