使用旋量几何技术对最小 N = 2、D = 4 德西特超重力的伪超对称解进行分类。我们找到了三类解决方案。第一类解决方案由几何结构组成，这些几何结构是配备高杜雄-托德结构的三维流形上的纤维化。第二类解是 Kastor 和 Traschen 的宇宙学 Majumdar-Papapetrou 解，第三类解对应于 Nariai 宇宙学中传播的引力波。
Pseudo-supersymmetric solutions of minimal N = 2, D = 4 de Sitter supergravity are classified using spinorial geometry techniques. We find three classes of solutions. The first class of solution consists of geometries which are fibrations over a three-dimensional manifold equipped with a Gauduchon–Tod structure. The second class of solution is the cosmological Majumdar–Papapetrou solution of Kastor and Traschen, and the third corresponds to gravitational waves propagating in the Nariai cosmology.
