Abstract
In , we consider a selfadjoint matrix strongly elliptic second order differential operator , . The coefficients of the operator are periodic and depend on . We study the asymptotic behavior of the operator , , in the small period limit. The principal term of approximation in the -norm for this operator is found. Approximation in the -operator norm with the correction term taken into account is also established. The error estimates are of the sharp order . The results are applied to homogenization for the solutions of the hyperbolic equation . As examples, we consider the acoustics equation, the system of elasticity, and the model equation of electrodynamics.
