Charles Livingston

AI总结:

本文定义了纽结协边群的射影空间及其整数值度量,通过环面纽结探索其基本性质,并利用扭结证明相关单纯复形包含任意大维度的无限单纯形集合。

摘要:

纽结协边群上的协边距离用于度量两个纽结接近线性相关的程度。粗略地说,d(K,J) 通过最小化包含 K 和 J 的循环子群中纽结对之间的协边距离来定义。精确化后,这引出了纽结协边群射影空间的定义。我们通过考虑环面纽结来探索该射影空间及其整数值度量基本性质。扭结被用来证明相关的单纯复形包含一个具有任意大维度的无限单纯形集合。

英文摘要:

The cobordism distance on the knot concordance group is used to define a measure of how close two knots are to being linearly dependent. Roughly stated, d(K,J) is defined by minimizing the cobordism distance between pairs of knots in cyclic subgroups containing K and J. When made precise, this leads to the definition of the projective space of the knot concordance group. We explore basic properties of this projective space and its integer-valued metric by considering torus knots. Twist knots are used to show that the associated simplicial complex contains an infinite set of simplices of arbitrarily large dimension.
