Exact renormalization group for O(4) gauged supergravity

We study exact the renormalization group (RG) in O(4) gauged supergravity using the effective average action formalism. The nonperturbative RG equations for cosmological and newtonian coupling constants are found. The existence is shown of (nonstable) fixed point of these equations. The solution of the RG equation for the newtonian coupling constant is qualitatively the same as in Einstein gravity (i.e. it is growing at large distances).
