Abstract: Investigation of a class of matrix periodic elliptic second-order differential operators $ {{\mathcal{A}}_\varepsilon}$ in $ {\mathbb{R}}{^d}$ with rapidly oscillating coefficients (depending on $ {{\mathbf{x}}/\varepsilon}$) is continued. The homogenization problem in the small period limit is studied. Approximation for the resolvent $ {({\mathcal{A}}_\varepsilon + I)^{-1}}$ in the operator norm from $ {L_2({\mathbb{R}}^d)}$ to $ H^1({\mathbb{R}}^d)$ is obtained with an error of order $ {\varepsilon}$. In this approximation, a corrector is taken into account. Moreover, the ( $ {L_2} \to {L_2}$)-approximations of the so-called fluxes are obtained.
