AI总结:

研究由闭双曲三维流形和简单闭测地线组成的对,利用Choi结果给出无前述正旋转理想三角剖分的例子,如Vol3及相关测地线,为Vol3无此类三角剖分猜想提供证据。

摘要:

利用Choi的一个结果,我们给出了第一组例子,它由一个闭双曲三维流形和一条简单闭测地线组成,使得对于该流形绕所选测地线旋转不存在正旋转理想三角剖分。在前两个例子中,闭流形是SnapPy普查中的第三个流形,即Vol3,测地线是其最短测地线和第二短测地线。这为Vol3对于任何测地线选择都没有正旋转理想三角剖分的猜想提供了证据。

英文摘要:

Using a result of Choi, we provide the first examples of pairs consisting of a closed hyperbolic three-manifold and a simple closed geodesic, such that there is no positive spun ideal triangulation for the manifold, spun about the chosen geodesic. In our first two examples, the closed manifold is the third manifold in the SnapPy census, also known as Vol3, and the geodesics are its systole and second systole. This provides evidence for the conjecture that Vol3 has no positive spun ideal triangulation for any choice of geodesic.
