Time dependent Quantum Gravity — •Aureliano Skirzewski and Martin Bojowald — c/o MPI fur Gravitationphysik, Albert Einstein Institut, Am Muhlenberg 1, 14476 Golm.

By introducing a simple mechanism to solve a single constraint system in the context of canonical quantization, we are able to give an answer to the problem of time. This allows us to develop time dependent physics in the context of quantum loop gravity. This work is intimately related to group averaging techniques in the sense that time appears as the parameter of the transformation introduced by the Hamiltonian operator.
