摘要：
The renormalization-group improved effective potential-to leading-log and in the linear curvature approximation-is constructed for ''finite'' theories in curved spacetime. It is not trivial and displays a quite interesting, exponential-like structure-in contrast with the case of flat spacetime where it coincides with the classical potential. Several possible cosmological applications, as curvature-induced phase transitions and modifications of the values of the gravitational and cosmological constants, are briefly discussed.
