　　《黎曼幾何》非常值得一讀。

內容簡介

　　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。

　　讀這本書時，偶然還想到瞭我們日常對狂狷的理解大都錯瞭。《論語·子路》中雲：“不得中行而與之，必也狂狷乎。狂者進取，狷者有所不為也。”狂狷一詞可以分開解，“狂”是對自己來說，“狷”是麵對這個世界來說——自我進取，追求超越，是為狂；沉默以對，不敏俗事，是為狷。反觀那些文青藝青，其狂不過作態，其狷更不必說。惟有一個人道德無虧，纔有資格評價那些道德有虧的。——“你們中間誰是沒有罪的，誰就可以先拿石頭打她。”（《約翰福音》）

1872年剋萊因在德國埃爾朗根大學作就職演講時，闡述瞭《埃爾朗根綱領》，用變換群對已有的幾何學進行瞭分類。在《埃爾朗根綱領》發錶後的半個世紀內，它成瞭幾何學的指導原理，推動瞭幾何學的發展，導緻瞭射影微分幾何、仿射微分幾何、共形微分幾何的建立。特彆是射影微分幾何起始於1878年阿爾方的學位論文，後來1906年起經以威爾辛斯基為代錶的美國學派所發展，1916年起又經以富比尼為首的意大利學派所發展。

　　當然，也還有另一個原因，野夫先生的嬉笑怒罵就是如此。他們是穿過黑暗年代的那一輩，忍受著屈辱與邊緣化的放逐。每每想到野夫先生在大理的一處昏暗酒館或者西藏青山下一夜一夜喝著酒，我就更能感到時代的罪惡。他們尚且還能瀟灑，而不能離開傢室的就更不必想。
