Il teorema del viriale e l'equilibrio di un sistema autogravitante isolato

The viriale theorem for continuous systems, is here established. The A., through this theorem, tries to achieve some information about the equilibrium of the insulated autograviting system. According to the theory of some Geologists, the Earth — during the geologic Eras — may be increased remarkably its own dimensions. The results attained in this paper are not clashing with above mentioned theory.
