摘要：

The renormalization-group improved effective potential for an arbitrary renormalizable massless gauge theory in curved spacetime is found, thus generalizing Coleman-Weinberg's approach corresponding to flat space. Some explicit examples are considered, among them: lambdaphi4 theory, scalar electrodynamics, the asymptotically-free SU(2) gauge model, and the SU(5) GUT theory. The possibility of curvature-induced phase transitions is analyzed. It is shown that such a phase transition may take place in a SU(5) inflationary universe. The inclusion of quantum gravity effects is briefly discussed.
