|Title:||Stability of a string inspired inflationary scenario|
|Abstract:||We consider an inflationary model inspired in the low energy limit of string theory. In this model, the scale factor grows exponentially with time, while the scalar fields are time independent. A perturbation study is performed, and we establish the conditions for such a model to be stable or not. These stability conditions can have consequences either for the structure formation and for the graceful exit problems.|
