BLACK-HOLES IN THE GAUGE THEORETIC FORMULATION OF DILATONIC GRAVITY

We show that two-dimensional topological BF theories coupled to partic les carrying non-Abelian charge admit a new coupling involving the Lag range multiplier field. When applied to the gauge theoretic formulatio n of dilatonic gravity it gives rise to a source term for the gravitat ional field, We show that the system admits black hole solutions.
