Abstract
The method of calculation of the effective potential (in linear curvat ure approximation and at any loop) in massless gauge theory in curved space-time by means of the direct solution of the renormalization grou p equation is given. The closed expression for the two-loop effective potential is obtained. The two-loop effective potential in lambdaphi4- theory is written explicitly. Some comments about it as well as about the two-loop effective potential in the standard model are presented.
