Heegaard弗洛尔同调的无穷味与整上同调环

On the Infinity Flavor of Heegaard Floer Homology and the Integral Cohomology Ring

Tye Lidman

摘要:

Ozsvath和Szabo构造了一个谱序列,其中E_2项Λ^*(H^1(Y;Z))\otimes Z[U,U^{-1}]收敛到HF^ \infty(Y,s).他们猜想微分完全由三重积分上积形式通过一个建议的公式确定。本文证明了当s为挠时,HF^ \infty(Y,s)实际上是由整上同调环决定的.此外,对于扭转Spin^c结构,我们给出了当b_1为3或4时,系数取模2的HF^ \infty的完整计算.

英文摘要:

Ozsvath and Szabo construct a spectral sequence with E_2 term Λ^*(H^1(Y;Z))\otimes Z[U,U^{-1}] converging to HF^\infty(Y,s) for a torsion Spin^c structure s. They conjecture that the differentials are completely determined by the integral triple cup product form via a proposed formula. In this paper, we prove that HF^\infty(Y,s) is in fact determined by the integral cohomology ring when s is torsion. Furthermore, for torsion Spin^c structures, we give a complete calculation of HF^\infty with mod 2 coefficients when b_1 is 3 or 4.
