内容简介

　　The object of this book is to familiarize the reader with the basic language of and some fundamental theorems in Riemannian Geometry. To avoid referring to previous knowledge of differentiable manifolds， we include Chapter 0， which contains those concepts and results on differentiable manifolds which are used in an essential way in the rest of the book。
　　The first four chapters of the book present the basic concepts of Riemannian Geometry (Riemannian metrics， Riemannian connections， geodesics and curvature). A good part of the study of Riemannian Geometry consists of understanding the relationship between geodesics and curvature. Jacobi fields， an essential tool for this understanding， are introduced in Chapter 5. In Chapter 6 we introduce the second fundamental form associated with an isometric immersion， and prove a generalization of the Theorem Egregium of Gauss. This allows us to relate the notion of curvature in Riemannian manifolds to the classical concept of Gaussian curvature for surfaces。

　　当然，也还有另一个原因，野夫先生的嬉笑怒骂就是如此。他们是穿过黑暗年代的那一辈，忍受着屈辱与边缘化的放逐。每每想到野夫先生在大理的一处昏暗酒馆或者西藏青山下一夜一夜喝着酒，我就更能感到时代的罪恶。他们尚且还能潇洒，而不能离开家室的就更不必想。

截面曲率、里奇曲率以及数量曲率是非常重要的几何量。研究这些量与黎曼流形的几何性质以及拓扑性质之间的关系是黎曼几何的一个重要课题。例如，嘉当－阿达马定理断言：若一个n维单连通完备黎曼流形的截面曲率处处不大于零，那么它与Rn微分同胚。再如迈尔斯定理断言：若完备黎曼流形的里奇曲率处处大于一个正常数h，那么它必是紧流形而且基本群有限。W.克林格贝格和M.伯热证明的球定理断言：如果完备单连通n维黎曼流形M的截面曲率KM 满足，那么M与n维欧氏球面Sn同胚。这些结果显示了流形的拓扑性质与度量性质之间有密切的联系。在这方面还有许多未解决的问题。
