摘要:

2010年,Turaev引入了knotoids作为结的一种变体,它用两个端点的闭区间的嵌入代替了圆的嵌入。各种各样的结不变量已被扩展到knotoid。在这里,我们提供了球面和平面knotoid双曲的定义。证明了双曲球面拟节面的乘积是双曲的,并且其体积是相加的,确定了有理球面拟节面的最小体积,并给出了各类双曲拟节面。我们还包括表的双曲卷球形和平面knotoids。

英文摘要:

In 2010, Turaev introduced knotoids as a variation on knots that replaces the embedding of a circle with the embedding of a closed interval with two endpoints. A variety of knot invariants have been extended to knotoids. Here we provide definitions of hyperbolicity for both spherical and planar knotoids. We prove that the product of hyperbolic spherical knotoids is hyperbolic and the volumes add. We also determine the least volume of a rational spherical knotoid and provide various classes of hyperbolic knotoids. We also include tables of hyperbolic volumes for both spherical and planar knotoids.
