If we consider the gravitational collapse of a material object to a blackhole, we would expect, for ranges of mass where a black hole would form, thefollowing scenario. A large enough object would collapse classically until anevent horizon forms, and to an external observer the object would be lost fomview. However, once the horizon has formed the black hole will begin to emitHawking radiation and the hole will lose mass and the horizon will shrink. Thefinal state of this process could be either a zero-mass "black hole" withconsequent information loss, or some sort of "quantum remnant.  A complete investigation of this process would require: 1) A complete andconsistent theory of quantum gravity coupled to some kind of field that wouldprovide the Hawking radiation (which could be the gravitational field itself--gravitons); 2) Some kind of definition of a "horizon" in this quantumgravity, and; 3) The calculational tools to achieve a description of thescenario. Lacking these, one may resort to toy models to try to give some sortof preliminary answer.  In this paper we will consider the collapse of an infinitesimally thin dustshell in 2+1 gravity, where an exact minisuperspace quantum solution exists,and try to make rough estimates of the collapse-Hawking radiation-remnantformation process.Comment: 28 pages, 13 figures, to appear in the proceedings of NEB XII,  Nauplion, Greec
