椭圆模函数理论讲义 第一卷 azw3 网盘 高速 下载地址大全 免费

Felix Klein著名的 Erlangen 纲领使得群作用理论成为数学的核心部分。在此纲领的精神下，Felix Klein开始一个伟大的计划，就是撰写一系列著作将数学各领域包括数论、几何、复分析、离散子群等统一起来。他的一本著作是《二十面体和十五次方程的解》于1884年出版，4年后翻译成英文版，它将三个看似不同的领域——二十面体的对称性、十五次方程的解和超几何函数的微分方程紧密地联系起来。之后Felix Klein和Robert Fricke合作撰写了四卷著作，包括椭圆模函数两卷本和自守函数两卷本。《椭圆模函数理论讲义 第一卷 》是对一本著作的推广，内容包含Poincare 和Klein 在自守形式的高度原创性的工作，它们奠定了Lie群的离散子群、代数群的算术子群及自守形式的现代理论的基础，对数学的发展起着巨大的推动作用。
