Abstract: To each $ {W^ \ast }$-dynamical system $ (\mathfrak{M},G,\alpha )$ corresponds canonically a $ {C^ \ast }$-dynamical system $ ({\mathfrak{M}^c},G,\alpha \vert{\mathfrak{M}^c})$. We show that the $ {C^ \ast }$-crossed product $ G{ \times _\alpha }{\mathfrak{M}^c}$ can be identified with a certain $ {C^ \ast }$-subalgebra of the $ {W^ \ast }$-crossed product $ G{ \times _\alpha }\mathfrak{M}$.
