代数（英文版·第二版）
出版时间：2012年版
内容简介
《代数（英文版.第2版）》由著名代数学家与代数几何学家michaelartin所著，是作者在代数领域数十年的智慧和经验的结晶。书中既介绍了矩阵运算、群、向量空间、线性算子、对称等较为基本的内容，又介绍了环、模型、域、伽罗瓦理论等较为高深的内容。本书对于提高数学理解能力，增强对代数的兴趣是非常有益处的。此外，本书的可阅读性强，书中的习题也很有针对性，能让读者很快地掌握分析和思考的方法。作者结合这20年来的教学经历及读者的反馈，对本版进行了全面更新，更强调对称性、线性群、二次数域和格等具体主题。本版的具体更新情况如下：新增球面、乘积环和因式分解的计算方法等内容，并补充给出一些结论的证明，如交错群是简单的、柯西定理、分裂定理等。修订了对对应定理、su2 表示、正交关系等内容的讨论，并把线性变换和因子分解都拆分为两章来介绍。新增大量习题，并用星号标注出具有挑战性的习题。《代数（英文版.第2版）》在麻省理工学院、普林斯顿大学、哥伦比亚大学等著名学府得到了广泛采用，是代数学的经典教材之一。
