AI中文摘要:
在[OS05]中,作者证明了与链环的skein序列相关的双分支覆盖的Heegaard Floer同调存在一个正合三角,并构造了一个从约化Khovanov同调到链环双分支覆盖的Heegaard Floer同调的谱序列。对于$L \subset S^3$中的链环$L$及其双分支覆盖$\Sigma(L)$,不变量$HF(\Sigma(L))$不捕获$\Sigma(L)$上自然对合的信息。本文研究$HF(\Sigma(L))$的等变版本,并证明类似的正合三角和谱序列对该等变版本成立。
英文摘要:
In [OS05] the authors proved an exact triangle for the Heegaard Floer homology of the double branched covers associated to a skein sequence of links, and constructed a spectral sequence from the reduced Khovanov homology to the Heegaard Floer homology of the double branched cover of a link. For $L \subset S^3$ a link and $Σ(L)$ its double branched cover, the invariant $HF(Σ(L))$ doesn't capture the information of the natural involution on $Σ(L)$. In this paper we study the equivariant version of $HF(Σ(L))$ and prove that similar exact triangle and spectral sequence hold for this equivariant version.
