对合Heegaard弗洛尔同调的应用

Applications of involutive Heegaard Floer homology

Kristen Hendricks, Jennifer Hom, Tye Lidman

摘要:

利用Heegaard弗洛尔同调定义了同调配边不变量。这个不变量同构于一个配备自旋结构的有理同调球面的约化Heegaard弗洛尔同调的和项,并且类似于Stoffregen的连接Seiberg-Witten弗洛尔同调。我们使用这个不变量来研究同调配边群的结构,并在此过程中,计算某些三流形族的对合校正项。

英文摘要:

We use Heegaard Floer homology to define an invariant of homology cobordism. This invariant is isomorphic to a summand of the reduced Heegaard Floer homology of a rational homology sphere equipped with a spin structure and is analogous to Stoffregen's connected Seiberg-Witten Floer homology. We use this invariant to study the structure of the homology cobordism group and, along the way, compute the involutive correction terms for certain families of three-manifolds.
