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 irrat ional rotation C-algebra, A(theta), for any irrational number theta, is an extension of a topologically simple group by GL2(Z).
