A remark on four-dimensional almost Kähler-Einstein manifolds with negative scalar curvature
Concerning the Goldberg conjecture, we will prove a result obtained by applying the result of Iton in terms of L2-norm of the scalar curvature.
On some four-dimensional almost Kähler Einstein manifolds
Concerning the intergarability of almost Kahler manifolds, it is known the conjecture by S. I. Goldberg that a compact almost Kahler Einstein manifold is Kahler. In this paper, we will give some positive partial answers to the conjecture.
On some 4-dimensional compact Einstein almost Kähler manifolds
Soit M=(M, J, ) une variete a 4 dimensions compacte d'Einstein presque de Kahler dont la courbure scalaire est non negative. Alors M est une variete de Kahler
