Almost Kahler 4-manifolds with J-invariant Ricci tensor and special Weyl tensor
Vestislav Apostolov, Tedi Draghici
We study the question of integrability of a compatible almost complex structure on a compact symplectic 4-manifold, under various natural assumptions on the curvature of the associ…

Local rigidity of certain classes of almost Kahler 4-manifolds
Vestislav Apostolov, John Armstrong, Tedi Draghici
We show that any non-Kahler, almost Kahler 4-manifold for which both the Ricci and the Weyl curvatures have the same algebraic symmetries as they have for a Kahler metric is locall…
