具有纽结分支的内链图

Intrinsically Linked Graphs with Knotted Components

Thomas Fleming

摘要:

我们构造一个图G,使得G到R^{3}的任何嵌入都包含两个分量的非分裂链,其中至少一个分量是非平凡结。此外,对于任意m < n,我们生成一个图H,使得H的每个嵌入都包含一个非分裂的n个分量链,其中至少m个分量是非平凡的结点。然后,我们把我们的注意力转向完全图,并表明,对于任何给定的n,每一个嵌入的足够大的完全图包含两个组件链接的环绕数是一个非零倍的n。

英文摘要:

We construct a graph G such that any embedding of G into R^{3} contains a nonsplit link of two components, where at least one of the components is a nontrivial knot. Further, for any m < n we produce a graph H so that every embedding of H contains a nonsplit n component link, where at least m of the components are nontrivial knots. We then turn our attention to complete graphs and show that for any given n, every embedding of a large enough complete graph contains a two component link whose linking number is a nonzero multiple of n.
