设Y是一个具有平凡第一同调的闭三元流形,KY是一个纽结.本文利用K的纽结不变量的滤同伦型,给出了Y上沿着K的整数运算的Heegaard Floer同调的一个刻画。作为这些技术的一个例子,我们计算了Riemann曲面上的非平凡圆丛的Heegaard Floer同调群(系数为Z= 2 Z)。57 M27; 57 M25
Let Y be a closed three-manifold with trivial first homology, and let K Y be a knot. We give a description of the Heegaard Floer homology of integer surgeries on Y along K in terms of the filtered homotopy type of the knot invariant for K . As an illustration of these techniques, we calculate the Heegaard Floer homology groups of non-trivial circle bundles over Riemann surfaces (with coefficients in Z=2Z). 57M27; 57M25
