On permanence of regularity properties II

Abstract

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