Phys. Rev. Lett. 48, 1220–1223 (1982)Cosmology for Grand Unified Theories with Radiatively Induced Symmetry BreakingReceived 25 January 1982; published in the issue dated 26 April 1982 The treatment of first-order phase transitions for standard grand unified theories is shown to break down for models with radiatively induced spontaneous symmetry breaking. It is argued that proper analysis of these transitions which would take place in the early history of the universe can lead to an explanation of the cosmological homogeneity, flatness, and monopole puzzles. © 1982 The American Physical Society URL:
