摘要：

We discuss exact renormalization group (RG) in R-2 gravity using the effective average action formalism, The truncated evolution equation for such a theory against the de Sitter background leads to a system of nonperturbative RC equations for cosmological and gravitational coupling constants. An approximate solution of these RG equations shows that antiscreening or screening behavior of the Newtonian coupling arises, depending on the higher-derivative coupling constants.
