我们考虑一类特殊的伪黎曼度量,承认积分对合。证明了相应度量的测地线流完全可积的一个充要条件。我们考虑的任何度量都属于一个度量大家族(层次),这个家族也允许对合中的积分。许多经典的和新的完全可积度量的例子都存在于这样的层次中。
We consider a special class of pseudo-Riemannian metrics that admit integrals in involution. A necessary and sufficient conditions for the complete integrability of the geodesic flows of the corresponding metrics is proved. Any of the metrics we consider lies in a big family (hierarchy) of metrics that also admit integrals in involution. Many classical and new examples of completely integrable metrics lie in such hierarchies.
