Abstract: Several pointwise estimates are proved for solutions of linear elliptic equations with measurable coefficients in smooth domains through the weighted $ L_d$-norm 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.
