This text for a second course in linear algebra is aimed at math majors and graduate students. The novel approach taken here banishes determinants to the end of the book and focuses on the central goal of linear algebra: understanding the structure of linear operators on vector spaces. The author has taken unusual care to motivate concepts and to simplify proofs. For example, the book presents--without having defined determinants--a clean proof that every linear operator on a finite-dimensional complex vector space (or an odd-dimensional real vector space) has an eigenvalue. A variety of interesting exercises in each chapter helps students understand and manipulate the objects of linear algebra. 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. Students are introduced to inner-product spaces in the first half of the book and shortly thereafter to the finite-dimensional spectral theorem. This second edition includes a new section on orthogonal projections and minimization problems. The sections on self-adjoint operators, normal operators, and the spectral theorem have been rewritten. New examples and new exercises have been added, several proofs have been simplified, and hundreds of minor improvements have been made throughout the text.

现在回头看,其实就是早先国内教法僵化,赶不上时代了,这本书又恰巧被引进过来,所以显得弥足珍贵。 ------------------------------------------------------------------- 给大学新生上的线性代数和高等数学课,也许是为了侧重灌输实用知识,教给学生的更多是一堆眼花缭乱的...
评分在看过一遍常规线代教材之后,再看这本书,可以看到新的视野。书写十分流畅,还标有作者的理解,后面的习题也很好,习题选择的视角也颇具特色。
评分以下内容是初读此书时写的,有些内容经过一段时间的学习发现许多并不准确,但也不想修改。此书在数学的学习中只能是基础中的基础(找professor时候说我认真学完了这本书他鄙视了一番,you should read xxxx, not liike Sheldon Axler),属于那种数学领域的入门级读物,要是真...
评分说起代数,我真是百感交集。 高等代数和数学分析基本上就是我大学四年以数学为专业的基础和全部。然而在大一的时候,我喜欢代数远远多过数分。代数可谓是一种带我抽象认识世界的一种方式。 而现在,我翻开这本广为人称道的线性代数教材,想复习以前不熟悉的特征值和特征向量...
评分第二遍看线性代数,有点也有:最明显的就是本书的讲解逻辑还是挺好的,例如告诉你矩阵乘积是为何这样定义的(这点要比我大学的教材好一万倍)。 这么好的书为啥我给了2颗星,因为这书我看到一半的时候就有一种日了狗的感觉,我买这本书是想温习一遍大学的线性代数,可这本书对...
觀點很新穎, 值得一看!
评分解决了一些我长久以来的问题...... 应该早点读的
