Abstract

Let θ\theta be a nondegenerate skew symmetric real dd by dd matrix, and let AθA_{\theta} be the corresponding simple higher dimensional noncommutative torus. Suppose that dd is odd, or that dd is greater or equal to 4 and the entries of θ\theta are not contained in a quadratic extension of Q\mathbb{Q}. Then AθA_{\theta} is isomorphic to the transformation group C*-algebra obtained from a minimal homeomorphism of a compact connected one dimensional space locally homeomorphic to the product of the interval and the Cantor set. The proof uses classification theory of C*-algebras.
