3 two simple families of models of disks based on Robertson-Walker solutions admitting Matter and Ricci collineations [16] are presented which satisfy all the energy conditions.
3 Disks from Robertson-Walker solutions admitting Matter and Ricci Collineations
As an example of the above presented formalism, we consider the thin disk models obtained by means of the "displace, cut and reflect" method applied to Robertson-Walker solutions admitting Matter and Ricci collineations.
