A NEW PROOF OF HARNACK'S INEQUALITY FOR ELLIPTIC PARTIAL DIFFERENTIAL EQUATIONS IN DIVERGENCE FORM
2007
Electronic Journal of Differential Equations
unpublished
In this paper we give a new proof of Harnack's inequality for elliptic operator in divergence form. We imitate the proof given by Caffarelli for operators in nondivergence form.
