چکیده
where the matrix a(y) = [ak`(y)] is symmetric and positive de nite a(y) > ¬ I with ¬ > 0. Its entries belong to L # (Y ) (Y is the cube ]0; 2 o [ N and subscript `#’ means that the space consists of Y -periodic functions). In the sequel, we will make various further length-scale regularity assumptions on the coe ̄ cients ak` which play a central role throughout the paper. Some of them are as follows:

W 1,p ESTIMATES FOR ELLIPTIC HOMOGENIZATION PROBLEMS IN NONSMOOTH DOMAINS
Let Lε = −div ` A ` x ε ́ ∇ ́ , ε > 0 be a family of second order elliptic operators with real, symmetric coefficients on a bounded Lipschitz domain Ω in Rn, subject to the Dirichlet boundary condition. Assuming that A(x) is periodic and belongs to VMO, we show that there exists δ > 0 independent of ε such that Riesz transforms ∇(Lε)−1/2 are uniformly bounded on Lp(Ω), where 1 < p < 3+δ if n ≥ 3,...
متن کاملUniform Estimates in Two Periodic Homogenization Problems
We analyze two partial diierential equations that are posed on perforated domains. We provide a priori estimates, that do not depend on the size of the perforation: a sequence of solutions is uniformly bounded in a Sobolev space of regular functions. The rst homogeniza-tion problem concerns the Laplace-and the mean-curvature operator with Neumann boundary conditions. We derive uniform Lipschitz...

This paper is concerned with the asymptotic behavior of solutions of stochastic differential equations dyt = dωt − ∇V (yt ) dt , y0 = 0. When d = 1 and V is not periodic but obtained as a superposition of an infinite number of periodic potentials with geometrically increasing periods [V (x)= ∑∞ k=0 Uk(x/Rk), where Uk are smooth functions of period 1, Uk(0)= 0, and Rk grows exponentially fast wi...
متن کاملQuantitative Homogenization of Analytic Semigroups and Reaction–diffusion Equations with Diophantine Spatial Frequencies
Based on an analytic semigroup setting, we first consider semilinear reaction–diffusion equations with spatially quasiperiodic coefficients in the nonlinearity, rapidly varying on spatial scale ε. Under periodic boundary conditions, we derive quantitative homogenization estimates of order ε on strong Sobolev spaces H in the triangle 0 < γ < min(σ − n/2, 2− σ). Here n denotes spatial dimension. ...
متن کاملError estimates in periodic homogenization with a non-homogeneous Dirichlet condition
In this paper we investigate the homogenization problem with a non-homogeneous Dirichlet condition. Our aim is to give error estimates with boundary data in H1/2(∂Ω). The tools used are those of the unfolding method in periodic homogenization.
