Abstract:

In this article, we give the three-sphere inequalities and three-ball inequalities for the singular elliptic equation div(A\nabla u)-Vu=0, and the three-ball inequalities on the characteristic plane and the three-cylinder inequalities for the singular parabolic equation ∂tu-div(A\nabla u)+Vu=0, where the singular potential V belonging to the Kato-Fefferman-Phong's class. Some applications are also discussed.

Key words: Three-sphere inequality, three-cylinder inequality, singular partial differential equation, Kato-Fefferman-Phongs class, Lipschitz domain
