Abstract
I discuss the semiclassical approximation for the Wheeler–DeWitt equation when applied to the CGHS model and spherically symmetric gravity. Special attention is devoted to the issues of Hawking radiation, decoherence of semiclassical states, and black hole entropy. 1 Dedicated to Tullio Regge on his sixty–fifth birthday.
