分支双覆盖Heegaard Floer链复形的反对角滤子

On the anti-diagonal filtration for the Heegaard Floer chain complex of a branched double-cover

Eamonn Tweedy

摘要:

Seidel和Smith对S^{3}中的一个纽结K引入了分次不动点辛Khovanov上同调群Kh_{symp,inv}(K),以及对带有S^{2}xS^{1}的一个副本的双分支覆盖的连通和,引入了一个收敛到Heegaard弗洛尔同调-hat群的谱序列。该谱序列的E^{1}-page同构于因子Kh_{symp,inv}(K)。Seidel和Smith证明了Kh_{symp,inv}是一个纽结不变量。我们在这里表明,他们的谱序列的较高的页面也结不变。

英文摘要:

Seidel and Smith introduced the graded fixed-point symplectic Khovanov cohomology group Kh_{symp,inv}(K) for a knot K inside S^{3}, as well as a spectral sequence converging to the Heegaard Floer homology-hat group for the connected sum of the double branched cover with a copy of S^{2}xS^{1}. The E^{1}-page of this spectral sequence is isomorphic to a factor of Kh_{symp,inv}(K). Seidel and Smith proved that Kh_{symp,inv} is a knot invariant. We show here that the higher pages of their spectral sequence are knot invariants also.
