內容簡介
This book treats that part of Riemannian geometry related to more classical topics in a very original, clear and solid style. Before going to Riemannian geometry, the author presents a more general theory of manifolds with a linear connection. Having in mind different generalizations of Riemannian manifolds, it is clearly stressed which notions and theorems belong to Riemannian geometry and which of them are of a more general nature. Much attention is paid to
transformation groups of smooth manifolds.Throughout the book, different aspects of symmetric spaces are treated The author successfully combines the co-ordinate and invariant approaches to differential geometry, which give the reader tools for practical calculations as well as a theoretical understanding of the subject. The book contains a very usefullarge appendix on foundations of differentiable manifolds and basic structures on them which makes it self contained and practically independent from other sources.
The results are well presented and useful for students in mathematics and theoretical physics, and for experts in these fields.The book can serve as a textbook for students doing geometry, as well as a reference book for professional mathematicians and physicists.

前言/序言
要使我國的數學事業更好地發展起來,需要數學傢淡泊名利並付齣更艱苦地努力。另一方麵,我們也要從客觀上為數學傢創造更有利的發展數學事業的外部環境,這主要是加強對數學事業的支持與投資力度,使數學傢有較好的工作與生活條件,其中也包括改善與加強數學的齣版工作。
科學齣版社影印一批他們齣版的好的新書,使我國廣大數學傢能以較低的價格購買,特彆是在邊遠地區工作的數學傢能普遍見到這些書,無疑是對推動我國數學的科研與教學十分有益的事。
這次科學齣版社購買瞭版權,一次影印瞭23本施普林格齣版社齣版的數學書,就是一件好事,也是值得繼續做下去的事情。大體上分一下,這23本書中,包括基礎數學書5本,應用數學書6本與計算數學書12本,其中有些書也具有交叉性質。這些書都是很新的,2000年以後齣版的占絕大部分,共計16本,其餘的也是1990年以後齣版的。這些書可以使讀者較快地瞭解數學某方麵的前沿,例如基礎數學中的數論、代數與拓撲三本,都是由該領域大數學傢編著的“數學百科全書”的分冊。對從事這方麵研究的數學傢瞭解該領域的前沿與全貌很有幫助。按照學科的特點,基礎數學類的書以“經典”為主,應用和計算數學類的書以“前沿”為主。這些書的作者多數是國際知名的大數學傢,例如《拓撲學》一書的作者諾維科夫是俄羅斯科學院的院士,曾獲“菲爾茲奬”和“沃爾夫數學奬”。這些大數學傢的著作無疑將會對我國的科研人員起到非常好的指導作用。
當然,23本書隻能涵蓋數學的一部分,所以,這項工作還應該繼續做下去。更進一步,有些讀者麵較廣的好書還應該翻譯成中文齣版,使之有更大的讀者群。
總之,我對科學齣版社影印施普林格齣版社的部分數學著作這一舉措錶示熱烈的支持,並盼望這一工作取得更大的成績。
