Einstein-Proca model, micro black holes, and naked singularities. (English) Zbl 0996.83075
It is thought, that in the early Universe numerous micro blackholes may have been created. The Einstein-Proca equations are studied in the static spherically-symmetric case, partly describing physical conditions of those exotic objects. Positive Proca terms suggest the possibility that some of these objects might be devoid of event horizons.
