Quantum corrections to two-dimensional gravity with external field
We introduce an external field and calculate the quantum corrections to the solutions of the 2d gravity, via the trace anomaly. We show that there are black hole type solutions even in the absence of the matter field and cosmological constant. We see also that these solutions are similar to that obt...
