Black holes as solitons
Abstract
The letter reports that a whole class of solitons is apparently available among the known exact classical Schwarzschildlike solutions to Einstein's equations. It is noted that the relevant solutions are steadystate, possess finite energy, and can be localized; the stability of some of these solutions depends on rather general considerations, but the association of a finite and conserved energy with asymptotically flat (localized) solutions follows from the existence of the energymomentum pseudotensor. The solitons are identified with fgravity black holes, and it is shown that although they are classically stable, these gravitational solitons may be able to decay through vacuum effects.
