An Introduction to the Theory of Groups

２０００年度の後期に伊藤達郎さんの群論の講義の演習担当として組ませて頂きました。 図書室から借りてきた Rotman の「An Introduction to the Theory of Groups」の中から自分が解きたい問題だけを抜き出して、勝手に楽しんでました。 https://t.co/kDyc1iy8lO https://t.co/WNQYeyusa9

Consider this 'durassien' notion of theatre as 'bavard' (talkative) against Poincaré's note on restraint in writing - “I tried writing this paper more succinctly, but it became too hard to understand, so I’d rather be seen as too chatty and be understood”:

Curious how to translate Poincaré here: ❝When I wanted to restrict myself, I fell (leapt?) into the unknown; I preferred to seem mute.❞ cc @IgorCarron? 🤔 Preface to 3rd ed. of J. Rotman's Intro to Theory of Groups (Springer Grad. Texts Maths #148) 📖 htt
