On Cohomological Decomposability of Almost-Kähler Structures

Daniele Angella, Adriano Tomassini, Weiyi Zhang

We study the J-invariant and J-anti-invariant cohomological subgroups of the de Rham cohomology of a compact manifold M endowed with an almost-Kähler structure (J, ω, g). In partic…

J-holomorphic curves in a nef class

Tian-Jun Li, Weiyi Zhang

Taubes established fundamental properties of holomorphic subvarieties in dimension 4 in \cite{T1}. In this paper, we further investigate properties of reducible holomorphic…

Almost Kahler forms on rational 4-manifolds

Tian-Jun Li, Weiyi Zhang

We study Nakai-Moishezon type question and Donaldson's "tamed to compatible" question for almost complex structures on rational four manifolds. By extending Taubes' subvarieties--c…
