　　《黎曼几何》非常值得一读。

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。

1872年克莱因在德国埃尔朗根大学作就职演讲时，阐述了《埃尔朗根纲领》，用变换群对已有的几何学进行了分类。在《埃尔朗根纲领》发表后的半个世纪内，它成了几何学的指导原理，推动了几何学的发展，导致了射影微分几何、仿射微分几何、共形微分几何的建立。特别是射影微分几何起始于1878年阿尔方的学位论文，后来1906年起经以威尔辛斯基为代表的美国学派所发展，1916年起又经以富比尼为首的意大利学派所发展。
