On Homogenization Of Elliptic Equations With Random Coefficients

Joseph G. Conlon, University of Michigan
Ali Naddaf, University of Michigan


Abstract
In this paper, we investigate the rate of convergence of the solution $u_ve$ of the random elliptic
partial difference equation $(nabla^{ve *} a(x/ve,om)nabla^ve+1)u_ve(x,om)=f(x)$
to the corresponding homogenized solution. Here $xinveZ^d$, and $ominOmega$
represents the randomness. Assuming that $a(x)$'s are independent and uniformly
elliptic, we shall obtain an upper bound $ve^alpha$ for the rate of convergence,
where $alpha$ is a constant which depends on the dimension $dge 2$ and the deviation
of $a(x,om)$ from the identity matrix. We will also show that the (statistical) average of
$u_ve(x,om)$ and its derivatives decay exponentially for large $x$.
