Recent investigations revealed that the explosive decay of the inflaton field takes place in the first stage of reheating due to the effect of parametric resonance (Kofman et al., 1994). One of surprising possibilities of the non-thermal fluctuations (created particles) during preheating is the symmetry restoration which may lead to the formation of topological defects (Kofman et al., 1996; Tkachev, 1996).
