Abstract
We consider an inflationary model inspired in the low energy limit of string theory. In this model, the scale factor grows exponentially wit h time, while the scalar fields are time independent. A perturbation s tudy is performed, and we establish the conditions for such a model to be stable or not. These stability conditions can have consequences ei ther for the structure formation and for the graceful exit problems.
