Local models and integrability of certain almost Kahler 4-manifolds
Vestislav Apostolov, John Armstrong, Tedi Draghici
We classify, up to a local isometry, all non-Kahler almost Kahler 4-manifolds for which the fundamental 2-form is an eigenform of the Weyl tensor, and whose Ricci tensor is invaria…

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…
