On the physical inner product of Quantum Gravity — •Benjamin Bahr — Albert-Einstein Institut, Am Muehlenberg 1, 14476 Golm/Potsdam

Additionally to solving the constraints in Loop Quantum Gravity, one of the still unsettled questions is how to equip the space of solutions with an inner product that allows for a physical interpretation of the theory. It will be shown how the combined techniques of Master constraint and coherent states provide an error-controlled approximation scheme for such a physical inner product. Furthermore, the scheme is tested on a simple cosmological model.
