Quantum group and Hopf algebra symmetries in (2+1)-gravity
We discuss the role of quantum group and Hopf algebra symmetries in (2+1)-gravity. In particular, we comment on the question which quantum groups are relevant for (2+1)-gravity and show that quantum group symmetries are also present in (2+1)-dimensional loop quantum gravity. Part of thhe talk is based on joint work with K. Noui and B. J. Schroers.
