In this paper, we consider surfaces in 4--dimensional pseudo--Riemannian space--forms with index 2. First, we obtain some of geometrical properties of such surfaces considering their relative null space. Then, we get classifications of quasi--minimal surfaces with positive relative nullity.

具有正相对零位的拟黎曼空间形式的拟极小曲面

在本文中,我们考虑指数为 2 的 4 维伪黎曼空间形式的曲面。首先,我们考虑了这些曲面的相对零空间,获得了这些曲面的一些几何特性。然后,我们得到具有正相对无效性的准极小曲面的分类。
