Abstract

For convex hypersurfaces in the affine space An+1\mathbb{A}^{n+1} (n2n\geq2), A.-M.\ Li introduced the notion of α\alpha-normal field as a generalization of the affine normal field. By studying a Monge-Amp\`ere equation with gradient blowup boundary condition, we show that regular domains in An+1\mathbb{A}^{n+1}, defined with respect to a proper convex cone and satisfying some regularity assumption if n3n\geq3, are foliated by complete convex hypersurfaces with constant Gauss-Kronecker curvature relative to the Li-normalization. When n=2n=2, a key feature is that no regularity assumption is required, and the result extends our recent work about the α=1\alpha=1 case.
