Description
I investigate the ultraviolet behaviour of quantum gravity within a functional renormalization
group approach. In particular, the scale- and momentum-dependence of the graviton propagator and the graviton three-point function are studied and the fixed point structure of the theory is analyzed.
Moreover, a novel locality property as an essential feature of a well-defined renormalization group flow is intrdouced and locality in quantum gravity is discussed.
