摘要：

We explicitly solve the one-loop renormalization group equations for a particular higher derivative quant im gravity and obtain the induced r-dependence of Newton's constant due to quantum fluctuations of the geometry. We then show how, by considering these effects, it may be possible to (a) reconcile nucleosynthesis bounds on the density parameter of the Universe with the predictions of inflationary cosmology, and (b) reproduce the inferred variation of the density parameter with distance. Our calculation can be interpreted as a computation of the contribution of gravitons to the (local) energy density of the Universe.
