Jai Grover, Jan B. Gutowski, Carlos A. R. Herdeiro, Wafic Sabra

摘要:

我们讨论了五维和四维复杂几何中允许最小超重力Killing旋量的解之间的关系。在无规范情况下(宇宙学常数为零Λ=0),解是根据超卡勒基空间确定的;在规范情况下(Λ<0),复几何是卡勒几何;在德西特情况下(Λ>0),复几何是有挠超卡勒几何(HKT)。在后者的情况下,一些细节的推导。在每种情况下,构造明确的解决方案的方法进行了讨论。

英文摘要:

We discuss the relation between solutions admitting Killing spinors of minimal supergravities in five dimensions and four dimensional complex geometries. In the ungauged case (vanishing cosmological constant Λ=0) the solutions are determined in terms of a hyper-Kahler base space; in the gauged case (Λ<0) the complex geometry is Kahler; in the de Sitter case (Λ>0) the complex geometry is hyper-Kahler with torsion (HKT). In the latter case some details of the derivation are given. The method for constructing explicit solutions is discussed in each case.
