Estimates of Nash-Aronson type for a diffusion equation with asymmetric matrix and their applications to homogenization
Vasilii Vasil'evich Zhikov · Sbornik Mathematics · 2006
A parabolic equation with asymmetric elliptic operator of the second order is considered. Estimates of the Nash-Aronson type are established in the case when the skew-symmetric part of the heat matrix is unbounded. These estimates are used in the proof of the central limit theorem for diffusion in an incompressible stochastic flow.
