Phys. Rev. D 60, 024010 (1999) [7 pages]Gravity from topological field theoryReceived 23 February 1999; published 14 June 1999 We construct a topological field theory which, on the one hand, generalizes BF theories in that there is a non-trivial coupling to “topological matter fields;” and, on the other, generalizes the three-dimensional model of Carlip and Gegenberg to arbitrary dimensional manifolds. Like the three dimensional model, the theory can be considered to describe a gravitational field interacting with topological matter. In particular, in two dimensions, the model is that of gravity on a torus. In four dimensions, the model is shown to admit constant curvature black hole solutions. © 1999 The American Physical Society URL:
