《華章數(shù)學(xué)原版精品系列:代數(shù)(英文版·第2版)》是作者在代數(shù)領(lǐng)域數(shù)十年的智慧和經(jīng)驗(yàn)的結(jié)晶。書中既介紹了矩陣運(yùn)算、群、向量空間、線性算子、對(duì)稱等較為基本的內(nèi)容,又介紹了環(huán)、模型、域、伽羅瓦理論等較為高深的內(nèi)容。本書對(duì)于提高數(shù)學(xué)理解能力,增強(qiáng)對(duì)代數(shù)的興趣是非常有益處的。此外,本書的可閱讀性強(qiáng),書中的習(xí)題也很有針對(duì)性,能讓讀者很快地掌握分析和思考的方法。
作者結(jié)合這20年來的教學(xué)經(jīng)歷及讀者的反饋,對(duì)本版進(jìn)行了全面更新,更強(qiáng)調(diào)對(duì)稱性、線性群、二次數(shù)域和格等具體主題。本版的具體更新情況如下:
新增球面、乘積環(huán)和因式分解的計(jì)算方法等內(nèi)容,并補(bǔ)充給出一些結(jié)論的證明,如交錯(cuò)群是簡(jiǎn)單的、柯西定理、分裂定理等。
修訂了對(duì)對(duì)應(yīng)定理、su2 表示、正交關(guān)系等內(nèi)容的討論,并把線性變換和因子分解都拆分為兩章來介紹。
新增大量習(xí)題,并用星號(hào)標(biāo)注出具有挑戰(zhàn)性的習(xí)題。
《華章數(shù)學(xué)原版精品系列:代數(shù)(英文版·第2版)》在麻省理工學(xué)院、普林斯頓大學(xué)、哥倫比亞大學(xué)等著名學(xué)府得到了廣泛采用,是代數(shù)學(xué)的經(jīng)典教材之一。
Michael Artin,當(dāng)代領(lǐng)袖型代數(shù)學(xué)家與代數(shù)幾何學(xué)家之一,美國(guó)麻省理工學(xué)院數(shù)學(xué)系榮譽(yù)退休教授。1990年至1992年,曾擔(dān)任美國(guó)數(shù)學(xué)學(xué)會(huì)主席。由于他在交換代數(shù)與非交換代數(shù)、環(huán)論以及現(xiàn)代代數(shù)幾何學(xué)等方面做出的貢獻(xiàn),2002年獲得美國(guó)數(shù)學(xué)學(xué)會(huì)頒發(fā)的Leroy P.Steele終身成就獎(jiǎng)。Artin的主要貢獻(xiàn)包括他的逼近定理、在解決沙法列維奇-泰特猜測(cè)中的工作以及為推廣“概形”而創(chuàng)建的“代數(shù)空間”概念。
