A Quantitative Central Limit Theorem for the Effective Conductance on the Discrete Torus

Journal Article (Journal Article)

We study a random conductance problem on a d-dimensional discrete torus of size L > 0. The conductances are independent, identically distributed random variables uniformly bounded from above and below by positive constants. The effective conductance A of the network is a random variable, depending on L, that converges almost surely to the homogenized conductance A . Our main result is a quantitative central limit theorem for this quantity as L → ∞. In particular, we prove there exists some σ > 0 such that d (L – A / σ, g) ≲ L log L,where d is the Kolmogorov distance and gis a standard normal variable. The main achievement of this contribution is the precise asymptotic description of the variance of A .© 2015 Wiley Periodicals, Inc. L hom K A hom K L d/2 –d/2 d
