缝合弗洛尔同调区分塞弗特曲面

Sutured Floer homology distinguishes between Seifert surfaces

Irida Altman

摘要:

我们展示了第一个例子中的一个结的三个领域与一对最小的亏格塞弗特表面,可以区分使用缝合弗洛尔同调的互补流形与自旋^c-分级。这回答了尤哈斯的一个问题。更精确地说,我们证明了补流形的缝合的弗洛尔同调的欧拉示性数区别于两个曲面,就像尤哈斯引入的缝合的弗洛尔多胞形一样。实际上,我们展示了一个无限的家庭结对塞弗特表面,可以区分的欧拉示性数。

英文摘要:

We exhibit the first example of a knot in the three-sphere with a pair of minimal genus Seifert surfaces that can be distinguished using the sutured Floer homology of their complementary manifolds together with the Spin^c-grading. This answers a question of Juhász. More precisely, we show that the Euler characteristic of the sutured Floer homology of the complementary manifolds distinguishes between the two surfaces, as does the sutured Floer polytope introduced by Juhász. Actually, we exhibit an infinite family of knots with pairs of Seifert surfaces that can be distinguished by the Euler characteristic.
