Abstract
The structure of the automorphism group of a simple C*-algebra of real rank zero which is an inductive limit of circle algebras is described. In particular, it is proved that the automorphism group of the irrational rotation C*-algebra,A ч, for any irrational number ч, is an extension of a topologically simple group by GL2(ℤ).
