内容摘要:

《代数基本定理》对数学中最重要的定理——代数基本定理给出了六种证明,方法涉及到分析、代数与拓扑等数学分支。《代数基本定理》的六个证明:两个分析方法中一个(本质上)是运用实分析中的两维极值定理,一个是运用标准的复分析方法,也就是经典的Liouville定理;两个代数方法中一个是运用多项式环的知识,一个是运用域扩张的Galois定理:两个拓扑方法中一个是运用分枝数的计算,另一个是运用单位球的基本群。此外附录中给出了Gauss的证明,cauchy的证明,三个另外的反分析证明以及两个另外的拓扑证明。 《代数基本定理》以一个问题为主线,纵横数学的几乎所有领域,结构严谨、文笔流畅、浅显易懂、引人入胜,是一本少见的能让读者入迷的好读物,可以使读者与作者在书中很好地进行对话与交流。通过学习《代数基本定理》,读者可以增加知识面,加深对学科交叉与渗透的理解和认识。不足之处是各种方法之间缺乏进行比较的描写和分析。 《代数基本定理》适合高年级大学生、研究生自学和讨论,特别适合于用作短学期教材或数学选修类课程教材。
