Abstract

A translation invariant state ω\omega on CC^*-algebra \clb=k\IZM(k)\clb=\otimes_{k \in \IZ}M^{(k)}, where M(k)=Md(\IC)M^{(k)}=M_d(\IC) is the dd-dimensional matrices over field of complex numbers, give rises a stationary quantum Markov chain and associates canonically a unital completely positive normal map τ\tau on a von-Neumann algebra \clm\clm with a faithful normal invariant state ϕ\phi. We give an asymptotic criteria on the Markov map (\clm,τ,ϕ)(\clm,\tau,\phi) for purity of ω\omega. Such a pure ω\omega gives only type-I or type-III factor ωR\omega_R once restricted to one side of the chain \clbR=\IZ+M(k)\clb_R=\otimes_{\IZ_+}M^{(k)}. In case ωR\omega_R is type-I, ω\omega admits Kolmogorov's property.
