本文研究了S. Ivanov和D. Vassilev引入的具有零曲率的qc-爱因斯坦流形的几种类型。其次,我们将在标准四元数空间的域y上构造一组四元数厄米度量,其中一个是Bochner平面度量Kähler。为此,我们对四元海森堡李群域x上的标准四元接触结构进行保形变形,得到商x上的四元厄米度量。
We study some types ofqc-Einstein manifolds with zeroqc-scalar curvature introduced by S. Ivanov and D. Vassilev. Secondly, we shall construct a family of quaternionic Hermitian metricson the domainYof the standard quaternion spaceone of which, sayis a Bochner flat Kähler metric. To do so, we deform conformally the standardquaternionic contact structureon the domainXof thequaternionic Heisenberg Lie groupto obtain quaternionic Hermitian metrics on the quotientYofXby.
