Title: Three-dimensional quantum gravity coupled to matter
Abstract: Three-dimensional quantum gravity with a cosmological constant can be defined using the Turaev-Viro state sum model. This quantum gravity model admits observables which are sources of matter along one dimensional world-lines with interactions at vertices. This allows the definition of the coupling of quantum gravity to Feynman diagrams of matter fields. Some properties of this definition will be explained.
