Abstract

We show that the hyperbolic manifold $\mathbb{H}^n/\mathbb{Z}^{n-2}$ is not rigid under all compactly supported deformations that preserve the scalar curvature lower bound $-n(n-1)$, and that it is rigid under deformations that are further constrained by certain topological conditions. In addition, we prove two related splitting results.

具有下有界标量曲率$\mathbb{H}^n/\mathbb{Z}^{n-2}$的刚性和非刚性

我们证明了双曲流形$\mathbb{H}^n/\mathbb{Z}^{n-2}$在所有保持标量曲率下界$-n(n-1)$的紧支撑变形下不是刚性的，并且在进一步受某些拓扑条件约束的变形下是刚性的。此外，我们还证明了两个相关的分裂结果。
