Let $X$ be a compact Hausdorff space and $\alpha$ be a homeomorphism of $X$.
So we have a natural action of $\mathbb{Z}$ on $C(X)$ which generates the cross product algebra $C^*(X,\alpha)$. [It is well known that this algebra is simple if and only if the dynamical system $(X,\alpha)$ is a minimal dynamical system, see corollaryCorollary VIII.3.9 of page 229 of the book C*$C^*$ Algebras by examples by Kenneth R. Davidson, "https://books.google.com/books?id=0TXteNfrzvcC&lpg=PA223&vq=minimal%20dynamical%20system&pg=PA229&output=embed" width=500 height=500)
Is there a precise example of a dynamical system whose minimality is not easy to proofprove but the symplicity simplicity of corresponding algebra is accessible and easy to investigationinvestigate?
Is there an example of a dynamical system with a finite number of minimal components whosesuch that the number of minimal components can be precisely observed in the corresponding cross product algebra?
