分裂环的化妆交叉猜想

The cosmetic crossing conjecture for split links

Joshua Wang

摘要:

给定一个分裂的两分量链路沿非平凡带的带和,我们通过在带上添加任意数量的全扭转来获得一个由整数索引的结族。我们证明了这个族中的纽结具有相同的Heegaard纽结弗洛尔同调和相同的瞬子纽结弗洛尔同调.相反,化妆品交叉猜想的推广预测,在这个家庭的结都是不同的。我们验证了这一预测表明,在这个家庭中的任何两个结有不同的Khovanov同源性。一路上,我们证明了三个结的同源检测平凡带。

英文摘要:

Given a band sum of a split two-component link along a nontrivial band, we obtain a family of knots indexed by the integers by adding any number of full twists to the band. We show that the knots in this family have the same Heegaard knot Floer homology and the same instanton knot Floer homology. In contrast, a generalization of the cosmetic crossing conjecture predicts that the knots in this family are all distinct. We verify this prediction by showing that any two knots in this family have distinct Khovanov homology. Along the way, we prove that each of the three knot homologies detects the trivial band.
