內容簡介

　　Riemannian geometry is characterized, and research is oriented towards and shaped by concepts (geodesics, connections, curvature, ...) and objectives, in particular to understand certain classes of (compact) Riemannian manifolds defined by curvature conditions (constant or positive or negative curvature, ...). By way of contrast, geometric analysis is a perhaps somewhat less systematic collection of techniques, for solving extremal problems naturally arising in geometry and for investigating and characterizing their solutions. It turns out that the two fields complement each other very well; geometric analysis offers tools for solving difficult problems in geometry, and Riemannian geometry stimulates progress in geometric analysis by setting ambitious goals.
　　It is the aim of this book to be a systematic and comprehensive introduction to Riemannian geometry and a representative introduction to the methods of geometric analysis. It attempts a synthesis of geometric and analytic methods in the study of Riemannian manifolds.
　　The present work is the sixth edition of my textbook on Riemannian geometry and geometric analysis. It has developed on the basis of several graduate courses I taught at the Ruhr~University Bochum and the University of Leipzig. The main new feature of the present edition is a systematic presentation of the spectrum of the Laplace operator and its relation with the geometry of the underlying Riemannian marufold. Naturally, I have also included several smaller additions and minor corrections (for which I am grateful to several readers). Moreover, the organization of the chapters has been systematically rearranged.

黎曼流形上的幾何學。德國數學傢G.F.B.黎曼19世紀中期提齣的幾何學理論。1854年黎曼在格丁根大學發錶的題為《論作為幾何學基礎的假設》的就職演說，通常被認為是黎曼幾何學的源頭。在這篇演說中，黎曼將麯麵本身看成一個獨立的幾何實體，而不是把它僅僅看作歐幾裏得空間中的一個幾何實體。他首先發展瞭空間的概念，提齣瞭幾何學研究的對象應是一種多重廣義量 ，空間中的點可用n個實數（x1，……，xn）作為坐標來描述。這是現代n維微分流形的原始形式，為用抽象空間描述自然現象奠定瞭基礎。這種空間上的幾何學應基於無限鄰近兩點（x1，x2，……xn）與（x1+dx1，……xn+dxn）之間的距離，用微分弧長度平方所確定的正定二次型理解度量。亦即 （gij）是由函數構成的正定對稱矩陣。這便是黎曼度量。賦予黎曼度量的微分流形，就是黎曼流形。

黎曼認識到度量隻是加到流形上的一種結構，並且在同一流形上可以有許多不同的度量。黎曼以前的數學傢僅知道三維歐幾裏得空間E3中的麯麵S上存在誘導度量ds2=Edu2+2Fdudv+Gdv2，即第一基本形式，而並未認識到S還可以有獨立於三維歐幾裏得幾何賦予的度量結構。黎曼意識到區分誘導度量和獨立的黎曼度量的重要性，從而擺脫瞭經典微分幾何麯麵論中局限於誘導度量的束縛，創立瞭黎曼幾何學，為近代數學和物理學的發展作齣瞭傑齣貢獻。
