在与杨晃的合作中,我们利用定向2-平面场的同伦类定义了Heegaard Floer同调的一个典范绝对分次。迈克尔·哈钦斯(Michael Hutchings)在嵌入接触同源性上定义了类似的分级。在本文中,我们表明,同构之间的这些同调理论定义的科林-Ghiggini-本田保持这种分级。
In joint work with Yang Huang, we defined a canonical absolute grading on Heegaard Floer homology by homotopy classes of oriented 2-plane fields. A similar grading was defined on embedded contact homology by Michael Hutchings. In this paper we show that the isomorphism between these homology theories defined by Colin-Ghiggini-Honda preserves this grading.
