淹没度量测地线流的可积性

On the integrability of geodesic flows of submersion metrics

Bozidar Jovanovic

摘要:

假设给定一个紧致黎曼流形(Q,g),其测地线流是完全可积的.设G是紧连通李群,它通过等距自由作用在Q上.自然的问题出现了:Q/G上的测地线流与淹没度规一起是可积的吗?在一个自然的假设下,我们证明答案是肯定的。得到了具有完全可积测地线流的流形的新例子。

英文摘要:

Suppose we are given a compact Riemannian manifold (Q,g)with completely integrable geodesic flow. Let G be a compact connected Lie group acting freely on Q by isometries. The natural question arises: will the geodesic flow on Q/G equipped with the submersion metric be integrable? Under one natural assumption, we prove that the answer is affirmative. New examples of manifolds with completely integrable geodesic flows are obtained.
