Abstract

In this article, we study the permanence of topological and algebraic dimension type properties of simple unital C\spC\sp*-algebras. When a pair of unital C\spC\sp*-algebras (A,B)(A, B) is associated by a *-homomorphism ϕ:AB\phi: A\to B which is tracially sequentially-split by order zero, we show that under suitable assumptions on either AA or BB, or both AA and BB \begin{itemize} \item tracial mm-comparison passes from BB to AA; \item tracial mm-almost divisibility passes from BB to AA; \item tracial nuclear dimension less than mm passes from BB to AA. \end{itemize}
