Symplectic forms and cohomology decomposition of almost complex 4-manifolds

Tedi Draghici, Tian-Jun Li, Weiyi Zhang

For any compact almost complex manifold $(M, J)$ , the last two authors defined two subgroups $H_{J}^{+} (M)$ , $H_{J}^{-} (M)$ of the degree 2 real de Rham cohomology group $H^2(M, \mathbb{R})…

The Kodaira Dimension of Lefschetz Fibrations

Josef G Dorfmeister, Weiyi Zhang

In this note, we verify that the complex Kodaira dimension $κ^{h}$ equals the symplectic Kodaira dimension $κ^{s}$ for smooth 4-manifolds with complex and symplectic structures. We als…
