An Isometrical $CP^{n}$ -Theorem

Xiaole Su, Hongwei Sun, Yusheng Wang

Let $M^{n} (n \geq 3)$ be a complete Riemannian manifold with $sec_{M} \geq 1$ , and let $M_{i}^{n_{i}}$ ( $i = 1, 2$ ) be two comlplete totally geodesic submanifolds in $M$ . We prove that if $n_…

On the Blaschke's Conjecture

Xiaole Su, Hongwei Sun, Yusheng Wang

The Blaschke's conjecture asserts that if $\diam(M)=\text{Inj}(M)=\frac\pi2$ (up to a rescaling) for a complete Riemannian manifold $M$ , then $M$ is isometric to $\Bbb S^n(\frac12)…

On $\frac{π}{2}$ -separated subsets of Alexandrov spaces with curvature $\geq 1$

Xiaole Su, Hongwei Sun, Yusheng Wang

Let $M$ be an $n$ -dimensional Alexandrov space with curvature $\geq 1$ , and let ${q_{1}, \dots, q_{k}}$ be any $\frac{π}{2}$ -separated subset in $M$ (i.e. the distance $|q_iq_j|\geq\fra…
