Cubulated moves and discrete knots

Gabriela Hinojosa, Alberto Verjosvky, Cynthia Verjovsky Marcotte

摘要:

本文证明了给定$\mathbb{R}^3$中的两个立方纽结$K_1$,$K_2$,它们是同位的当且仅当其中一个可以通过一个有限序列的立方移动从一个到另一个.这些动作类似于经典驯服结的Reidemeister动作。我们使用的事实是,一个立方结是由一个轮换的连续顶点的$\mathbb{Z}^3$ -格(有一些限制),描述一些经典的不变量和属性的结在这样的轮换,通过投影到一个平面上,使它是单射时,限制到$\mathbb{Z}^3$ -格和图像的$\mathbb{Z}^3$ -格是密集的。

英文摘要:

In this paper, we prove than given two cubic knots $K_1$, $K_2$ in $\mathbb{R}^3$, they are isotopic if and only if one can pass from one to the other by a finite sequence of cubulated moves. These moves are analogous to the Reidemeister moves for classical tame knots. We use the fact that a cubic knot is determined by a cyclic permutation of contiguous vertices of the $\mathbb{Z}^3$-lattice (with some restrictions), to describe some of the classic invariants and properties of the knots in terms of such cyclic permutations, by projecting onto a plane such that it is injective when restricted to the $\mathbb{Z}^3$-lattice and the image of the $\mathbb{Z}^3$-lattice is dense.
