证明了非负标量曲率度量的比较定理,也称为Gromov的二面体刚性猜想:对于n≤7,如果n维棱镜具有非负标量曲率和弱平均凸面,则它的二面角不可能处处不大于其欧几里德模型,除非它与欧几里德棱镜等距.证明依赖于构造黎曼多面体中的某些自由边界极小超曲面,并推广了Schoen-Yau的降维思想。我们的结果是正质量定理的一个局部化。
We prove the following comparison theorem for metrics with nonnegative scalar curvature, also known as the dihedral rigidity conjecture by Gromov: for n ≤ 7, if an n -dimensional prism has nonnegative scalar curvature and weakly mean convex faces, then its dihedral angle cannot be everywhere not larger than its Euclidean model, unless it is isometric to an Euclidean prism. The proof relies on constructing certain free boundary minimal hypersurface in a Riemannian polyhedron, and extending a dimension descent idea of Schoen-Yau. Our result is a localization of the positive mass theorem.
