Abstract

Let Ω\Omega be a class of unital C{\rm C^*}-algebras which have the second type tracial nuclear dimensional at moat nn (or have tracial nuclear dimensional at most nn). Let AA be an infinite dimensional unital simple C{\rm C^*}-algebra such that AA is asymptotical tracially in Ω\Omega. Then T2dimnuc(A)n{\rm T^2dim_{nuc}}(A)\leq n (or Tdimnuc(A)n{\rm Tdim_{nuc}}(A)\leq n). As an application, let AA be an infinite dimensional simple separable amenable unital C{\rm C^*}-algebra with T2dimnuc(A)n{\rm T^2dim_{nuc}}(A)\leq n (or Tdimnuc(A)n{\rm Tdim_{nuc}}(A)\leq n). Suppose that α:GAut(A)\alpha:G\to {\rm Aut}(A) is an action of a finite group GG on AA which has the tracial Rokhlin property. Then T2dimnuc(C(G,A,α))n{\rm T^2dim_{nuc}}({{\rm C^*}(G, A,\alpha)})\leq n (or Tdimnuc{\rm Tdim_{nuc}} (C(G,A,α))n({{\rm C^*}(G, A,\alpha)})\leq n).
