Drinfeld Doubles for Finite Subgroups of SU(2) and SU(3) Lie Groups

Coquereaux, R.; Zuber, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)

Drinfeld doubles of finite subgroups of SU(2) and SU(3) are investigated in detail. Their modular data – S, T and fusion matrices – are computed explicitly, and illustrated by means of fusion graphs. This allows us to ...
Notes on TQFT Wire Models and Coherence Equations for SU(3) Triangular Cells

Coquereaux, R.; Isasi, E.; Schieber, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2010)

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 fusion graphs that describe modules associated ...
Quantum Symmetries for Exceptional SU(4) Modular Invariants Associated with Conformal Embeddings

Coquereaux, R.; Schieber, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)

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 these embeddings, or from their ...
