We evaluate the friction term of the evolution equation of the order parameter in the new inflationary universe scenario. It is shown that the friction force is too weak so that the order parameter travels many time around minima of the Coleman-Weinberg potential. It causes unwanted large scale inhomogeneities. Reheating of the universe is also discussed. |
