Weighted aleksandrov estimates: PDE and stochastic versions

Research output: Contribution to journalArticle

Abstract

Several pointwise estimates are proved for solutions of linear elliptic equations with measurable coefficients in smooth domains through the weighted Ldnorm of the free term. The weights allow the free term to blow up near the boundary. Weighted estimates for occupation times of diffusion processes are also presented.
