## Abstract

Abstract We give renormalizations for λø d+1 4 which lead for any d to rigorous upper and lower bound effective potentials which are finite (apart from a common divergent constant) and interacting. This proves that the corresponding exact effective potential has the same features. As this is known to be wrong for d>3 we conclude that even exact effective potentials can see interaction where there is none. They either have to be further qualified or should be traded for effective actions.
