翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Self-linking number ： ウィキペディア英語版 Self-linking number In knot theory, the self-linking number is an invariant of framed knots. It is related to the linking number of curves. A framing of a knot is a choice of a non-tangent vector at each point of the knot. Given a framed knot ''C'', the self-linking number is defined to be the linking number of ''C'' with a new curve obtained by pushing points of ''C'' along the framing vectors. Given a Seifert surface for a knot, the associated Seifert framing is obtained by taking a tangent vector to the surface pointing inwards and perpendicular to the knot. The self-linking number obtained from a Seifert framing is always zero. The blackboard framing of a knot is the framing where each of the vectors points in the vertical (''z'') direction. The self-linking number obtained from the blackboard framing is called the Kauffman self-linking number of the knot. This is not a knot invariant because it is only well-defined up to regular isotopy. ==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「Self-linking number」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.
