David Judgenate either at the black holes .. and .. (types (I) and (II)), or at infinity (type (III)). The limits of these three types of orbits are Cantor sets, defined by the unstable periodic orbits, that form a set of measure zero. In the case of particles with elliptic energy there are some stable periodi

Martin Smithgeneities of the distribution of galaxies by means of the Tolman solution of Einstein’s field equations for spherically symmetric dust in comoving coordinates. Such model is based on earlier works developed by L. Pietronero and J. R. Wertz on Newtonian cosmology, and the main points of these models
