Abstract

We study a pair of CC^*-algebras by associating a *-homomorphism from AA to BB allowing an approximate left-inverse to the sequence algebra of AA in a manner reminiscent of several tracial approximation properties. We are particularly interested how regularity properties in the Elliott classification program pass from BB to AA. Among them, we show that the strict comparison property and Z\mathcal{Z}-stability pass from BB to AA in our setting.
