Spectral Measures and Generating Series for Nimrep Graphs in Subfactor Theory II: SU (3)

چکیده
We complete the computation of spectral measures for SU(3) nimrep graphs arising in subfactor theory, namely the SU(3) ADE graphs associated with SU(3) modular invariants and the McKay graphs of finite subgroups of SU(3). For the SU(2) graphs the spectral measures distill onto very special subsets of the semicircle/circle, whilst for the SU(3) graphs the spectral measures distill onto very special subsets of the discoid/torus. The theory of nimreps allows us to compute these measures precisely. We have previously determined spectral measures for some nimrep graphs arising in subfactor theory, particularly those associated with all SU(2) modular invariants, all subgroups of SU(2), the torus T2, SU(3), and some SU(3) graphs.

Braided Subfactors, Spectral Measures, Planar algebras and Calabi-Yau algebras associated to SU (3) modular invariants
Braided subfactors of von Neumann algebras provide a framework for studying two dimensional conformal field theories and their modular invariants. We review this in the context of SU(3) conformal field theories through corresponding SU(3) braided subfactors and various subfactor invariants including spectral measures for the nimrep graphs, A2-planar algebras and almost Calabi-Yau algebras.
متن کاملSpectral Measures for G2 II: finite subgroups
Joint spectral measures associated to the rank two Lie group G2, including the representation graphs for the irreducible representations of G2 and its maximal torus, nimrep graphs associated to the G2 modular invariants have been studied. In this paper we study the joint spectral measures for the McKay graphs of finite
متن کاملSpectral Measures of Small Index Principal Graphs
Abstract. The principal graph X of a subfactor with finite Jones index is one of the important algebraic invariants of the subfactor. If ∆ is the adjacency matrix of X we consider the equation ∆ = U + U. When X has square norm ≤ 4 the spectral measure of U can be averaged by using the map u → u, and we get a probability measure ε on the unit circle which does not depend on U . We find explicit ...
متن کاملOcneanu Cells and Boltzmann Weights for the SU (3) ADE Graphs
We determine the cells, whose existence has been announced by Ocneanu, on all the candidate nimrep graphs except E 4 proposed by di Francesco and Zuber for the SU(3) modular invariants classified by Gannon. This enables the Boltzmann weights to be computed for the corresponding integrable statistical mechanical models and provide the framework for studying corresponding braided subfactors to re...
متن کاملAn Obstruction to Subfactor Principal Graphs from the Graph Planar Algebra Embedding Theorem
We find a new obstruction to the principal graphs of subfactors. It shows that in a certain family of 3-supertransitive principal graphs, there must be a cycle by depth 6, with one exception, the principal graph of the Haagerup subfactor. This is the published version of arXiv:1302.5148. A II1 subfactor is an inclusion A ⊂ B of infinite von Neumann algebras with trivial centre and a compatible ...
