内容简介

　　The present volume is the second in the author's series of three dealing with abstract algebra. For an understanding of this volume a certain familiarity with the basic concepts treated in Volume I: groups， rings， fields， homomorphisms， is presup- posed. However， we have tried to make this account' of linear algebra independent of a detailed knowledge of our first volume. References to specific results are given occasionally but some of the fundamental concepts needed have been treated again. In short， it is hoped that this volume can be read with complete understanding by any student who is mathematically sufficiently mature and who has a familiarity with the standard notions of modern algebra.

The present Vrolume completes the series of texts on algebra which the author began more than ten years ago. The account of field theory and Galois theory which we girre here is based on the notions and results of general algebra which appear in our first volume and on the more elementary parts of the second volume， dealing with linear algebra. The level of the present work .is roughly the same as that of Volume II.

比如我们10岁以前，阿拉丁神灯这一类儿童书籍能够打动我们，也能够让我们开始学着认识这个世界。然而当我们长大一些之后，能够打动我们或者对我们有巨大帮助的书籍，会变化。所以第一个建议是：根据自己当前的人生阶段、认知水平来思考自己应该看哪一类书，比如说初入职场的人，去学习具体的工作技能（如Excel的使用）会比研读管理学理论要更为有益，因为对于这个阶段的你来说，技能性的东西可以现学现练，很快就能把书里的东西转化为自己能力的一部分。

人都是有局限性的，「提升自我」这件事不只是技能上的提升，更核心的是视野、理念、思维方式这些意识世界里的东西。「读史使人明智，读诗使人灵秀，数学使人周密，科学使人深刻，伦理学使人庄重，逻辑修辞之学使人善辩：凡有所学，皆成性格。」第
