Notes on TQFT Wire Models and Coherence Equations for SU(3) Triangular Cells
Robert Coquereaux, Esteban Isasi, Gil Schieber
After a summary of the TQFT wire model formalism we bridge the gap from Kuperberg equations for SU(3) spiders to Ocneanu coherence equations for systems of triangular cells on fusi…
Quantum symmetries for exceptional SU(4) modular invariants associated with conformal embeddings
Robert Coquereaux, Gil Schieber
Three exceptional modular invariants of SU(4) exist at levels 4, 6 and 8. They can be obtained from appropriate conformal embeddings and the corresponding graphs have self-fusion.…
From conformal embeddings to quantum symmetries: an exceptional SU(4) example
Robert Coquereaux, Gil Schieber
We briefly discuss several algebraic tools that are used to describe the quantum symmetries of Boundary Conformal Field Theories on a torus. The starting point is a fusion category…
Orders and dimensions for sl(2) or sl(3) module categories and Boundary Conformal Field Theories on a torus
Robert Coquereaux, Gil Schieber
After giving a short description, in terms of action of categories, of some of the structures associated with sl(2) and sl(3) boundary conformal field theories on a torus, we provi…
From modular invariants to graphs: the modular splitting method
E. Isasi, Gil Schieber
We start with a given modular invariant M of a two dimensional su(n)_k conformal field theory (CFT) and present a general method for solving the Ocneanu modular splitting equation…
Comments about quantum symmetries of SU(3) graphs
R. Coquereaux, D. Hammaoui, G. Schieber +1
For the SU(3) system of graphs generalizing the ADE Dynkin digrams in the classification of modular invariant partition functions in CFT, we present a general collection of algebra…
