Abstract
We introduce an external field to calculate the quantum corrections to the solutions of 2d gravity, via trace anomaly. We show that there ar e black-hole-type solutions even in the absence of a matter field and the cosmological constant. We also see that these solutions are simila r to the ones obtained from dilaton two-dimensional gravity.
