In this note, we show that for a closed almost-Kähler manifold ( X , J ) with the almost complex structure J satisfies dim ker P J = b 2 − 1 the space of de Rham harmonic forms is contained in the space of symplectic-Bott–Chern harmonic forms. In particular, suppose that X is four-dimensional, if the self-dual Betti number b 2 + = 1 , then we prove that the second non-HLC degree measures the gap between the de Rham and the symplectic-Bott–Chern harmonic forms.

关于闭辛流形的第二非HLC度
在这篇笔记中,我们展示了对于一个封闭的几乎 Kähler 流形( X , Ĵ ) 具有几乎复杂的结构Ĵ 满足暗淡 克尔 磷 Ĵ = b 2 - 1 de Rham 调和形式的空间包含在辛-Bott-Chern 调和形式的空间中。特别是,假设X 是四维的,如果自对偶贝蒂数b 2 + = 1 ,然后我们证明第二个非 HLC 度测量了 de Rham 和辛-Bott-Chern 谐波形式之间的差距。
