缝合弗洛尔同调与Seifert曲面的等价性

On sutured Floer homology and the equivalence of Seifert surfaces

Matthew Hedden, Andras Juhasz, Sucharit Sarkar

摘要:

研究了缝合流形的缝合弗洛尔同调不变量,该缝合流形是通过沿Seifert曲面割取纽结补而得到的。我们表明,这些不变量是精细的结弗洛尔同调,它们包含的“顶项”。特别是,我们使用缝合弗洛尔同调来区分两个非同位素的最小亏格塞弗特表面的结8_3。这种技术的一个关键因素是找到适当的Heegaard图缝合流形相关联的塞弗特曲面的补充。

英文摘要:

We study the sutured Floer homology invariants of the sutured manifold obtained by cutting a knot complement along a Seifert surface, R. We show that these invariants are finer than the "top term" of the knot Floer homology, which they contain. In particular, we use sutured Floer homology to distinguish two non-isotopic minimal genus Seifert surfaces for the knot 8_3. A key ingredient for this technique is finding appropriate Heegaard diagrams for the sutured manifold associated to the complement of a Seifert surface.
