==== 🔶 fλの定義がわかりづらかった根本原因 ==== ここをはっきり整理してみましょう: | 原因 | 説明 | | ------------- | --------------------------------------------------- | | 1. 記法の階層が深い | fλ の定義には、集合記法・直積・添字の操作・条件部の多変数的依存、などが重なっている。 | | 2. 文脈が省略されている | fλ が何のために必要なのか(積位相を作るための素材である)、が定義の文だけでは見えづらい。 | | 3. 例がない | 具体例(たとえばR³での具体的な開集合や直積集合)が最初から出ていれば、fλの意図がつかみやすくなる。 |
