Let $beta: S^{2n+1}to S^{2n+1}$ be a minimal homeomorphism ($nge 1$). We show that the crossed product $C(S^{2n+1})rtimes_{beta} Z$ has rational tracial rank at most one. More generally, let $Omega$ be a connected compact metric space with finite covering dimension and with $H^1(Omega, Z)={0}.$ Suppose that $K_i(C(Omega))=Zoplus G_i$ for some finite abelian group $G_i,$ $i=0,1.$ Let $beta: OmegatoOmega$ be a minimal homeomorphism. We also show that $A=C(Omega)rtimes_{beta}Z$ has rational tracial rank at most one and is classifiable. In particular, this applies to the minimal dynamical systems on odd dimensional real projective spaces. This was done by studying the minimal homeomorphisms on $Xtimes Omega,$ where $X$ is the Cantor set.
Let $X$ be an infinite compact metric space with finite covering dimension and let $alpha, beta : Xto X$ be two minimal homeomorphisms. We prove that the crossed product $C^*$-algebras $C(X)rtimes_alphaZ$ and $C(X)rtimes_beltaZ$ are isomorphic if and
We investigate some ergodic and spectral properties of general (discrete) $C^*$-dynamical systems $({mathfrak A},Phi)$ made of a unital $C^*$-algebra and a multiplicative, identity-preserving $*$-map $Phi:{mathfrak A}to{mathfrak A}$, particularising
We provide some properties and characterizations of homologically $UV^n$-maps and $lc^n_G$-spaces. We show that there is a parallel between recently introduced by Cauty algebraic $ANR$s and homologically $lc^n_G$-metric spaces, and this parallel is s
A compact space $X$ is said to be minimal if there exists a map $f:Xto X$ such that the forward orbit of any point is dense in $X$. We consider rigid minimal spaces, motivated by recent results of Downarowicz, Snoha, and Tywoniuk [J. Dyn. Diff. Eq.,
In this paper, we accomplish two objectives. Firstly, we extend and improve some results in the theory of (semi-)strongly self-absorbing C*-dynamical systems, which was introduced and studied in previous work. In particular, this concerns the theory
