摘要：
The asymptotically safe gravity is investigated in the framework of the functional renormalization group method. The low energy region of the model can account for the cosmological behavior, where it is assumed that the nonlocal effects play a crucial role. Using the Wegner-Houghton equation it is shown that the dynamically induced bilocal term modifies the infrared scaling of the model.
