Query: Wave Functional of Quantum Black Holes in Two Dimensions   The wheeler-DeWitt method is applied to the quantization of the 1 + 1
dimensional dilaton gravity coupled with the conformal matter fields. Exact
solutions to the WD equations are found, which are interpreted as
right(left)-moving black holes.
