前言/序言

　　Group Theory is a vast subject and， in this Introduction （as well as in theearlier editions）， I have tried to select important and representative theoremsand to organize them in a coherent way. Proofs must be clear， and examplesshould illustrate theorems and also explain the presence of restrictive hypo-theses. ！ also believe that some history should be given so that one canunderstand the origin of problems and the context in which the subjectdeveloped.　Just as each of the earlier editions differs from the previous one in a signifi-cant way， the present （fourth） edition is genuinely different from the third.Indeed， this is already apparent in the Table of Contents. The book nowbegins with the unique factorization of permutations into disjoint cycles andthe parity of permutations; only then is the idea of group introduced. This isconsistent with the history of Group Theory， for these first results on permu-tations can be found in an 1815 paper by Cauchy， whereas groups of permu-tations were not introduced until 1831 （by Galois）But even if history wereotherwise， I feel that it is usually good pedagogy to introduce a generalnotion only after becoming comfortable with an important special case. Ihave also added several new sections， and I have subtracted the chapter onHomologieal Algebra （although the section on Horn functors and charactergroups has been retained） and the section on Grothendieck groups.　The format of the book has been changed a bit： almost all exercises nowoccur at ends of sections， so as not to interrupt the exposition. There areseveral notational changes from earlier editions： I now write insteadof　to denote "H is a subgroup of G"; the dihedral group of order2n is now denoted by　instead of by ; the trivial group is denoted by ！instead of by {1}; in the discussion of simple linear groups， I now distinguishelementary traesvections from more general transvections;

羅特曼是一個數學傢，依據如下的事實，他的批評是特彆中肯的：皮亞傑的基本模式是符閤邏輯的，他經常參照集體稱為“布爾巴基”的法國數學傢小組。羅特曼指齣，皮亞傑誤解瞭數學的本質，特彆是數學進步中證明的作用。數學的主體是一種連貫的結構，但是證明的技術不是該結構的組成部分。他說，“數學的確由證明關於結構的主張所組成。……隻有對語言尤其是數學語言待貧乏作用的觀點，纔能支持皮亞傑提供的分析。”
