In this paper, we define D+J operator that is a generalized ∂∂ operator on higher dimensional almost Kähler manifolds. In terms of D+J operator, we study ∂-problem in almost Kähler geometry and the generalized Monge-Ampère equation on almost Kähler manifolds. Similarly to the Kähler case, we obtain C^∞ a priori estimates for the solution of the generalized Monge-Ampère equation on the almost Kähler manifold (M,ω,J) depended only on ω and J. Then as done in Kähler geometry, we study Calabi conjecture for almost Kähler manifolds. Finally, we will pose some questions in almost Kähler geometry.
