Abstract

We establish interior C2 estimates for convex solutions of the scalar curvature equation and the σ2-Hessian equation. We also prove interior curvature estimates for isometrically immersed hypersurfaces (Mn,g)Rn+1 with positive scalar curvature. These estimates are consequences of interior estimates for these equations obtained under a weakened condition.
