Homogenization of Neumann problem for hyperbolic stochastic partial differential equations in perforated domains

摘要

In this paper, we investigate a linear hyperbolic stochastic partial differential equation (SPDE) with rapidly oscillating epsilon-periodic coefficients in a domain with small holes (of size-epsilon) under Neumann conditions on the boundary of the holes and Dirichlet condition on the exterior boundary. When the number of these holes approach infinity, i.e. their sizes approach zero, the homogenized problem is a hyperbolic SPDE with constant coefficients in the domain without perforations. Moreover the convergence of the associated energy to that of the homogenized system is established.
