Abstract : Based on the Hilbert $C^*$-module structure we study the reconstruction theorem for stationary monotone quantum Markov processes from quantum dynamical semigroups. We prove that the quantum stochastic monotone process constructed from a covariant quantum dynamical semigroup is again covariant in the strong sense.
Keywords : Hilbert $C^{*}$-module, covariant representation, quantum stochastic process, quantum dynamical semigroup
