Abstract: We study symmetry restoration in a curved-background metric. Massless scalar QED is considered in the de Sitter space-time. The radius of the cosmological-event horizon corresponding to the critical temperature turns out to be of the order of the Compton wave-length of the vector bosom Quite similarly, the Gross-Neveau model in the twodimensional Schwarzschild background shows symmetry restoration when the radius of the black-hole horizon becomes comparable with the Compton wave-length of the spinor.
