内容摘要
书是版权引进自泰勒公司的英文原版教科书。本书对经典的二次无理数论给出了统一处理.材料以一种现代和初等代数的安排形式呈现，作者着重介绍了等价、连分数、二次特征标、二次阶、二元二次型和类群本书强调了二元形式的高斯理论与二次阶算法之间的联系，汇集了此前难以理解的和散落在文献中的理论的基本结果，包括二元二次丢番图方程、显式连分数、四次类群特征标、类数的16可除性、F.梅尔滕斯（F,Mertens)对高斯加倍定理的证明，以及一个脱离了基本判别式的二元二次型理论.本书还证明了等差数列中素数的迪利克雷定理，涵盖了迪利克雷的类数公式，证明了每一个初等二元二次形式表示无穷多个素数.在附录中给出了学习代数和初等数论所必需的基本知识。
