Some ergodic properties for infinite graphs associated with subfactors
Published online by Cambridge University Press: 14 October 2010
Abstract
We prove that the restriction of the graph of a subfactor, ΓN,M, to an infinite subset of vertices with finite boundary has the same norm as ΓN,W. In particular, if N φ M is extremal with [M : N] > 4 and ΓN,M has an A∞, tail then ΓN, M = A∞.
