Fusion 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 کاملThe non-chiral fusion rules in rational conformal field theories
We introduce a general method in order to construct the non-chiral fusion rules which determine the operator content of the operator product algebra for rational conformal field theories. We are particularly interested in the models of the complementary D−like solutions of the modular invariant partition functions with cyclic center ZN . We find that the non-chiral fusion rules have a ZN−gradin...
متن کاملTime - like Superselection Rules in Conformal Quantum Field Theory
In conformally invariant quantum field theories one encounters besides the standard DHR superselection theory based on spacelike (Einsteincausal) commutation relations and their Haag duality another timelike (”Huygens”) based superselection structure. Whereas the DHR theory based on spacelike causality of observables confirmed the Lagrangian internal symmetry picture on the level of the physica...
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...
