　　《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。

随后，由于黎曼几何的发展和爱因斯坦广义相对论的建立，微分几何在黎曼几何学和广义相对论中的得到了广泛的应用，逐渐在数学中成为独具特色、应用广泛的独立学科。

很喜欢多卡莫的书，这本先收着以后看。

评分☆☆☆☆☆

近代微分几何的创始人是黎曼，他在1854年创立了黎曼几何（实际上黎曼提出的是芬斯勒几何），这成为近代微分几何的主要内容，并在相对论有极为重要的作用。埃利·嘉当和陈省身等人曾在微分几何领域做出极为杰出的贡献。

很好的一本书，就是有点老了

任一仿紧微分流形总具有黎曼度量，这种黎曼度量的数目是非常繁多的，但也不是完全任意的。微分流形的度量结构是受它的拓扑结构所制约的，而这种制约关系正是黎曼几何研究的一个重要内容，还存在许多没有解决的问题。

很好，包装的很好，物流也很快，还有全新塑封。
