几类殆Kahler 4-流形的局部刚性

Local rigidity of certain classes of almost Kahler 4-manifolds

Vestislav Apostolov, John Armstrong, Tedi Draghici

摘要:

我们证明了任何非Kahler的几乎Kahler四维流形,其Ricci和Weyl曲率具有与Kahler度量相同的代数对称性,局部等距于O.科瓦尔斯基

英文摘要:

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 locally isometric to the (only) proper 3-symmetric 4-dimensional space described by O. Kowalski.
