Scientific paper

We consider inhomogeneous preheating in multi-field models of cosmological
perturbation. After preheating, two fields are trapped at an enhanced symmetric
point. One field is an oscillating field and the other is a light field that
plays an important role in generating perturbation. In this presentation, we
consider two types of potential for the light field.
