自從1908年出版以來，這本書已經(jīng)成為一部經(jīng)典之著。一代又一代嶄露頭角的數(shù)學(xué)家正是通過這本書的指引，步入了數(shù)學(xué)的殿堂。
在本書中，作者懷著對教育工作的無限熱忱，以一種嚴(yán)格的純粹學(xué)者的態(tài)度，揭示了微積分的基本思想、無窮級數(shù)的性質(zhì)以及包括極限概念在內(nèi)的其他題材。
作者簡介
G. H.Hardy英國數(shù)學(xué)家(1877—1947)。1896年考入劍橋三一學(xué)院，并子1900年在劍橋獲得史密斯獎。之后，在英國牛津大學(xué)。劍橋大學(xué)任教，是20世紀(jì)初著名的數(shù)學(xué)分析家之一。
他的貢獻(xiàn)包括數(shù)論中的丟番圖逼近、堆壘數(shù)論、素?cái)?shù)分布理論與黎曼函數(shù)，調(diào)和分析中的三角級數(shù)理論。發(fā)散級數(shù)求和與陶伯定理。不等式、積分變換與積分方程等方面，對分析學(xué)的發(fā)展有深刻的影響。以他的名字命名的Hp空間(哈代空間)，至今仍是數(shù)學(xué)研究中十分活躍的領(lǐng)域。
除本書外，他還著有《不等式》、《發(fā)散級數(shù)》等10多部書籍與300多篇文章。
