我们给出了由HK/QK对应得到的四元数Kähler度量的一个显式公式。作为应用,我们给出了Ferrara-Sabharwal度规及其单圈变形是四元数Kähler的一个新的证明.一个类似的显式公式给出了类似的(K/K)之间的对应Kähler流形赋予一个哈密尔顿Killing向量场。作为一个例子,我们应用这个公式的情况下,一个任意的锥形凯勒流形。
We give an explicit formula for the quaternionic Kähler metrics obtained by the HK/QK correspondence. As an application, we give a new proof of the fact that the Ferrara–Sabharwal metric as well as its one-loop deformation is quaternionic Kähler. A similar explicit formula is given for the analogous (K/K) correspondence between Kähler manifolds endowed with a Hamiltonian Killing vector field. As an example, we apply this formula in the case of an arbitrary conical Kähler manifold.
