摘要:
　Based on recent work of T. Draghici, T.-J. Li and W. Zhang, we further investigate properties of the dimension h_J^- of the J-anti-invariant cohomology subgroup of a closed almost Hermitian 4-manifold (M; g; J; F) using metric compatible almost complex structures. We prove that h_J^- = 0 for generic almost complex structures J on M.
　　　This is a joint work with Hongyu Wang,Ying Zhang and Peng Zhu.
