Pythagorean Theorem & curvature with lower or upper bound

Xiaole Su, Hongwei Sun, Yusheng Wang

In this paper, we give a comparison version of Pythagorean Theorem to judge the lower or upper bound of the curvature of Alexandrov spaces (including Riemannian manifolds).

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…
