Felix Klein著名的 Erlangen 綱領(lǐng)使得群作用理論成為數(shù)學(xué)的核心部分。在此綱領(lǐng)的精神下,F(xiàn)elix Klein開始一個偉大的計劃,就是撰寫一系列著作將數(shù)學(xué)各領(lǐng)域包括數(shù)論、幾何、復(fù)分析、離散子群等統(tǒng)一起來。他的一本著作是《二十面體和十五次方程的解》于1884年出版,4年后翻譯成英文版,它將三個看似不同的領(lǐng)域——二十面體的對稱性、十五次方程的解和超幾何函數(shù)的微分方程緊密地聯(lián)系起來。之后Felix Klein和Robert Fricke合作撰寫了四卷著作,包括橢圓模函數(shù)兩卷本和自守函數(shù)兩卷本。弗里克、克萊因著季理真主編迪普雷譯的《自守函數(shù)理論講義(第1卷)(英文版)(精)》是對一本著作的推廣,內(nèi)容包含Poincare 和Klein 在自守形式的高度原創(chuàng)性的工作,它們奠定了Lie群的離散子群、代數(shù)群的算術(shù)子群及自守形式的現(xiàn)代理論的基礎(chǔ),對數(shù)學(xué)的發(fā)展起著巨大的推動作用。
