Abstract
In the space \(\mathbb R^d\), we consider matrix elliptic operators \(L_\varepsilon\) of arbitrary even order \(2m\ge 4\) with measurable \(\varepsilon\)-periodic coefficients, where \(\varepsilon\) is a small parameter. We construct an approximation to the resolvent of this operator with an error of the order of \(\varepsilon^2\) in the operator \((L^2\to L^2)\)-norm.
