美容手术和非可定向曲面

Cosmetic surgeries and non-orientable surfaces

Kazuhiro Ichihara

摘要:

通过考虑surgered流形中的非可定向曲面,我们证明了2-桥结$9_{27} = S(49,19)$上的10/3-和-10/3-Dehn手术不是化妆品,即,它们给出了互不同胚的流形。根据先前已知的结果,特别是通过使用卡森不变量和Heegaard弗洛尔同调,该结是未知的,没有整容手术。

英文摘要:

By considering non-orientable surfaces in the surgered manifolds, we show that the 10/3- and -10/3-Dehn surgeries on the 2-bridge knot $9_{27} = S(49,19)$ are not cosmetic, i.e., they give mutually non-homeomorphic manifolds. The knot is unknown to have no cosmetic surgeries by previously known results; in particular, by using the Casson invariant and the Heegaard Floer homology.
