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。

人都是有局限性的,「提升自我」這件事不隻是技能上的提升,更核心的是視野、理念、思維方式這些意識世界裏的東西。「讀史使人明智,讀詩使人靈秀,數學使人周密,科學使人深刻,倫理學使人莊重,邏輯修辭之學使人善辯:凡有所學,皆成性格。」第
