- Also, General Relativity defines non-inertia space-time as a space of Riemann. For Riemann space has positive curvature, we have to doubt about where the minus curvature space is. 廣義相對論把非慣性時(shí)空定義為黎曼空間,但由于黎曼幾何是正曲率空間,既然廣義時(shí)空是對稱(chēng)的,我們必然要問(wèn),負曲率空間到哪去了?
- The well?known Funk metric ?F? is a projectively flat Finsler metric with constant curvature ?K=-14? and constant S?curvature ?S=12(n+1)F?. Funk度量F是一個(gè)射影平坦的Finsler度量;它具有常曲率K=-14和常S 曲率S=12(n+1)F.
- The paper gives some conditions that a 2-harmonic space-like submanifole of a pseudo-Riemannian manifold of negative constant curvature is a maximal space-like submanifold. 用活動(dòng)標架法給出了負常曲率的偽黎曼流形的2-調和子流形成為極大類(lèi)空子流形的充分條件。
