__Abstract:__

Let $\alpha \colon S^{2n+1} \to S^{2n+1}$ be a minimal homeomorphism ($n \ge 1$). We show that
the crossed product $C(S^{2n+1})\rtimes_\alpha \mathbb{Z}$ has rational tracial
rank at most one.
Let $\Omega$ be a connected compact metric space with finite covering
dimension and
with $H^1(\Omega, \mathbb{Z})=\{ 0 \}.$ Suppose that $K_0(C(\Omega))=\mathbb{Z} \oplus G_0$ and
$K_1(C(\Omega))=\mathbb{Z} \oplus G_1,$ where $G_0$ and $G_1$ are finite abelian
groups.
Let $\beta: \Omega \to \Omega$ be a minimal homeomorphism. We also show that
$A=C(\Omega) \rtimes_\beta \mathbb{Z}$ has rational tracial rank at most one and is
${\cal A}.$
In particular, this applies to the minimal dynamical systems on
odd dimensional real projective spaces.
