活动基点与链环弗洛尔同调的诱导自同构

Moving basepoints and the induced automorphisms of link Floer homology

Sucharit Sarkar

摘要:

给定定向三元流形Y中的l-分支指向定向链环(L,p),可以构造其链环链复形多项式环F_2[U_1,.,U_l]。将基点p_i在连接分量L_i中移动一圈,导出CFL(Y,L,p)的自同构。本文研究了CFL(Y,L,p)的一个用全纯圆盘显式定义的自同构(可能是不同的一个);对于S^3中的链,我们证明了这两个自同构是相同的。

英文摘要:

Given an l-component pointed oriented link (L,p) in an oriented three-manifold Y, one can construct its link Floer chain complex CFL(Y,L,p) over the polynomial ring F_2[U_1,...,U_l]. Moving the basepoint p_i in the link component L_i once around induces an automorphism of CFL(Y,L,p). In this paper, we study an automorphism (a possibly different one) of CFL(Y,L,p) defined explicitly in terms of holomorphic disks; for links in S^3, we show that these two automorphisms are the same.
