On geodesic in the space of the group rotation parameters

Бесплатный доступ

It is proved that the geodesic principle for the free rotation of a rigid body is realized in the parameter space of the rotation group. Namely, it is shown that a free rotation of a rigid body corresponds, in the Riemannian space of the rotation group parameters, to a curve, which is a geodesic relative to the Killing-Cartan metrics of the rotation group.
