All Irrational Extended Rotation Algebras are AF Algebras
Published online by Cambridge University Press: 20 November 2018
Abstract
Let $\theta \,\in \,\left[ 0,\,1 \right]$ be any irrational number. It is shown that the extended rotation algebra ${{B}_{\theta }}$ introduced by the authors in J. Reine Angew. Math. 665(2012), pp. 1–71, is always an $\text{AF}$ algebra.
