Abstract

We define a new notion of affine subspace concentration conditions for lattice polytopes, and prove that they hold for smooth and reflexive polytopes with barycenter at the origin. Our proof involves considering the slope stability of the canonical extension of the tangent bundle by the trivial line bundle and with the extension class $c_1(\mathcal{T}_X)$ on Fano toric varieties.

仿射子空间集中条件
我们定义了点阵多面体仿射子空间集中条件的新概念,并证明了它们适用于质心位于原点的光滑和自反多面体。我们的证明涉及考虑平凡线束和扩展类$c_1(\mathcal{T}_X)$在Fano toricvarieties上切束的正则扩展的斜率稳定性。
