| Abstract: | The purpose of this paper is to develop a canonical formulation of the rotational motion for an elastic Earth model. We have
obtained the canonical equations for the precession and nutation motion in an inertial frame, and from this we have deduced
the equations in an Earth-fixed frame. The linearized equations deduced for polar motion are equivalent to those obtained
using Liouville's equations. |
