Abstract

In this paper, we introduce a class of generalized tracial approximation C{\rm C^*}-algebras. Let P\mathcal{P} be a class of unital C{\rm C^*}-algebras which have tracially Z\mathcal{Z}-absorbing (tracial nuclear dimension at most nn, SP\rm SP property, mm-almost divisible, weakly (m,n)(m, n)-divisible). Then AA has tracially Z\mathcal{Z}-absorbing (tracial nuclear dimension at most nn, SP\rm SP property, weakly mm-almost divisible, secondly weakly (m,n)(m, n)-divisible) for any simple unital C{\rm C^*}-algebra AA in the class of this generalized tracial approximation C{\rm C^*}-algebras. As an application, Let AA be an infinite dimensional unital simple C{\rm C^*}-algebra, and let BB be a centrally large subalgebra of AA. If BB is tracially Z\mathcal{Z}-absorbing, then AA is tracially Z\mathcal{Z}-absorbing. This result was obtained by Archey, Buck and Phillips in \cite{AJN}.
