摘要
对于中的给定纽结,若对中任意纽结进行-手术所得流形与对进行-手术所得流形在保定向同胚下同胚,则必有,此时称斜率为的特征斜率。本文尝试寻找环面结的特征斜率。我们证明,任何大于的斜率都是的特征斜率。证明使用了Heegaard Floer同调与Agol–Lackenby六定理。对于,通过应用更多Heegaard Floer同调技巧,我们获得了其特征斜率集合的更具体信息。

备注
Version 2: 19 pages. This is a major revision. The title of the first version was "Towards a Dehn surgery characterization of $T_{5,2}$". We extended the result in the first version to general torus knots. We also fixed a gap in the first version, so our result for $T_{5,2}$ is slightly weaker than the originally claimed one
