Weighted estimates of solutions to second order parabolic equations

We evaluate the rate of decay for solutions to second order parabolic equations, which vanish on the boundary, while the right-hand side is allowed to be unbounded. Our approach is based on a special growth lemma, and it works for both divergence and non-divergence equations, in domains satisfying a general "exterior measure condition" (A). The result for elliptic case is published in Cho and Safonov (2007) [2]. (C) 2009 Elsevier Inc. All rights reserved.
