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