G3-homogeneous gravitational instantons

F. Bourliot, J. Estes, P. M. Petropoulos, Ph. Spindel

摘要:

本文给出了三维齐性空间上的自对偶四维引力瞬子的一个详尽的分类,即四维欧氏空间上的齐性自对偶度量,该空间允许Bianchi单传递等距群.分类模式基于Bianchi群和对偶群SO(3)的代数同态。新的和一般的解决方案被发现比安奇III。

英文摘要:

We provide an exhaustive classification of self-dual four-dimensional gravitational instantons foliated with three-dimensional homogeneous spaces, i.e. homogeneous self-dual metrics on four-dimensional Euclidean spaces admitting a Bianchi simply transitive isometry group. The classification pattern is based on the algebra homomorphisms relating the Bianchi group and the duality group SO(3). New and general solutions are found for Bianchi III.
