Introduction

Abstract

The Earth, its environment and the celestial bodies in the Universe are not static: they move, rotate and undergo deformations. The study of their kinematics and the dynamics that are behind is one of the major tasks of geodesy, geophysics and astronomy. Without trying to be exhaustive, let us mention some of the dynamical phenomena that currently concern these sciences:Lithospheric plate motionsEarth and oceanic tidesLoading effects on the Earth's crustPolar motionEarth's rotationDynamical behaviour of the Earth-Moon systemMotion of planets and satellitesRotation of planets and satellitesMotions of stars in the GalaxyDynamics of star clustersEvolution of star association and open clustersDifferential rotation of the GalaxyMotion in clusters of galaxiesEtc…
