A note on exact forms on almost complex manifolds

Tedi Draghici, Weiyi Zhang

Reformulations of Donaldson's "tamed to compatible" question are obtained in terms of spaces of exact forms on a compact almost complex manifold $(M^{2 n}, J)$ . In dimension 4, we sh…

On the J-anti-invariant cohomology of almost complex 4-manifolds

Tedi Draghici, Tian-Jun Li, Weiyi Zhang

For a compact almost complex 4-manifold $(M, J)$ , we study the subgroups $H_{J}^{\pm}$ of $H^{2} (M, R)$ consisting of cohomology classes representable by $J$ -invariant, respect…
