Sheldon Axler is Dean of the College of Science & Engineering at San Francisco State University. He has authored many well-received books including Precalculus: A Prelude to Calculus, Algebra & Trigonometry, College Algebra, A Glimpse at Hilbert Space Operators, Harmonic Function Theory, and Holomorphic Spaces.
New edition extensively revised and updated
Covers new topics such as product spaces, quotient spaces, and dual spaces
Features new visually appealing format for both print and electronic versions
Includes almost three times the number of exercises as the previous edition
This best-selling textbook for a second course in linear algebra is aimed at undergrad math majors and graduate students. The novel approach taken here banishes determinants to the end of the book. The text focuses on the central goal of linear algebra: understanding the structure of linear operators on finite-dimensional vector spaces. The author has taken unusual care to motivate concepts and to simplify proofs. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra.
The third edition contains major improvements and revisions throughout the book. More than 300 new exercises have been added since the previous edition. Many new examples have been added to illustrate the key ideas of linear algebra. New topics covered in the book include product spaces, quotient spaces, and dual spaces. Beautiful new formatting creates pages with an unusually pleasant appearance in both print and electronic versions.
No prerequisites are assumed other than the usual demand for suitable mathematical maturity. Thus the text starts by discussing vector spaces, linear independence, span, basis, and dimension. The book then deals with linear maps, eigenvalues, and eigenvectors. Inner-product spaces are introduced, leading to the finite-dimensional spectral theorem and its consequences. Generalized eigenvectors are then used to provide insight into the structure of a linear operator.
From reviews of previous editions:
“… a didactic masterpiece”
—Zentralblatt MATH
“… a tour de force in the service of simplicity and clarity … The most original linear algebra book to appear in years, it certainly belongs in every undergraduate library.”
—CHOICE
The determinant-free proofs are elegant and intuitive.
—American Mathematical Monthly
“Clarity through examples is emphasized … the text is ideal for class exercises … I congratulate the author and the publisher for a well-produced textbook on linear algebra.”
—Mathematical Reviews
##真的是越學越覺得Axler這本問題大,正文材料太簡單然後練習題的難度又完全不相稱。所謂的一開始就從抽象概念(Linear map)而不是傳統的Matirx講起確實是不錯,不過因為各個材料平均施力完全看不齣重點可以說是最大的敗筆。強烈不建議隻看這本,如果想學好Lin alg應該再加那本fin dim vector spaces, 對dual, spectrum theorem, Jordan form還有matrix的理解會好很多。
評分##考研的時候上過李永樂的綫性代數課,學到瞭很多計算方法和做題技巧,但僅限於這個層麵,對於一些綫性代數的insight完全不懂。最近在準備考博復習的時候,《矩陣論》這本書看的實在是太卡殼瞭,決定還是先補一下綫性代數的基礎知識,對綫性代數的認識不能隻停留在計算層麵,在知...
評分 評分##(碩士期間上矩陣分析課時看過一部分)這本書的視角比較偏數學係,完全以最抽象的方式來構建整個綫代知識體係。本書可以改名為《如何重新理解綫性代數》。適閤作為綫代進階。
評分 評分##其實綫性代數也不能這樣學……正文全是引理、定理和推論的堆砌,課後習題量較大且比較刁鑽,並不是很利於鞏固所學的內容。學下來的體會就是:雖然刷瞭幾百道習題,但兩個月一過正文的內容就已經忘得差不多瞭。
評分 評分 評分##昨晚終於看完,終於在最後一章幾乎最後一節見到瞭我們熟悉的行列式…… 全書不是用國內的那種行列式,矩陣的方法來說明綫性空間和綫性代數。 證明過程也都很簡潔優美,不需要傳統的矩陣式的證明。 裏麵有些符號和國內的標準有些不同……不過側邊欄的一些小知識很有意思
