关于调和分布的两点注记

Two notes on harmonic distributions

Kamil Niedzialomski

摘要:

我们说一个分布是调和的,如果它被看作格拉斯曼丛的一个截面时是调和的。我们用两种不同的方法在某些黎曼流形上找到了调和分布的新例子,并证明了调和分布的非线性。首先,我们提升分布到第二个切丛配备Sasaki度量。其次,我们在基流形上共形变形度量。

英文摘要:

We say that a distribution is harmonic if it is harmonic when considered as a section of a Grassmann bundle. We find new examples of harmonic distributions and show nonexistense of harmonic distrubutions on some Riemannian manifolds by two different approaches. Firstly, we lift distributions to the second tangent bundle equipped with the Sasaki metric. Secondly, we deform conformally the metric on a base manifold.
