Let $C$ be the Cantor set, let $p$ be the point $(\backslash tfrac,\; \backslash tfrac)\backslash in\backslash mathbb\; R^2$, and let $L(c)$, for $c\; \backslash in\; C$, denote the line segment connecting $(c,0)$ to $p$. If $c\; \backslash in\; C$ is an endpoint of an interval deleted in the Cantor set, let $X\_\; =\; \backslash$; for all other points in $C$ let $X\_\; =\; \backslash$; the Knaster–Kuratowski fan is defined as $\backslash bigcup\_\; X\_$ equipped with the subspace topology inherited from the standard topology on $\backslash mathbb^2$. The fan itself is connected, but becomes totally disconnected upon the removal of $p$. ==References== * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Knaster–Kuratowski fan」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
