本書是一部深入介紹抽象代數(shù)的入門書籍,被許多讀者奉為經(jīng)典。本書假定讀者了解了微積分和線性代數(shù),旨在讓讀者盡可能多的了解群、環(huán)、以及域理論的有關(guān)知識。本書特色之一是基礎(chǔ)部分內(nèi)容詳實(shí),講解扎實(shí),可以為讀者打下良好的基礎(chǔ),對于讀者更進(jìn)一步的學(xué)習(xí)代數(shù)大有助益。為了滿足更多讀者的要求,本書還包含了很多有關(guān)拓?fù)渲械耐{(diào)群和同調(diào)群的計算以加深對因子群的理解。書中內(nèi)容淺顯易懂,理論闡述清晰,條理分明,且大都以例子和練習(xí)的形式,便于直觀了解。為了將同調(diào)群講述的更加清楚,本書在第6版的基礎(chǔ)上減少了自動機(jī)、二進(jìn)制線性。
