论文摘要
打结的高度是衡量与结的距离。在这里,我们定义了高度的正和负部分,并证明它们确定了未签名的高度。某些多项式不变性为签名高度提供了下限。我们还研究了一组与结的序列。
The height of a knotoid is a measure of how far it is from being a knot. Here we define the positive and negative parts of the height, and we prove that they determine the unsigned height. Some polynomial invariants provide lower bounds for the signed heights. We also study a set of sequences associated to a knotoid.
