我们证明,通过在整数同调球 L 空间中拼接两个非平凡结补获得的整数同调球具有严格大于 1 的 Heegaard Floer 同源性。特别是,拼接 3 球体中非平凡结的补集永远不会产生 L 空间。该证明使用有界弗洛尔同调。
We show that the integer homology sphere obtained by splicing two nontrivial knot complements in integer homology sphere L-spaces has Heegaard Floer homology of rank strictly greater than one. In particular, splicing the complements of nontrivial knots in the 3-sphere never produces an L-space. The proof uses bordered Floer homology.
