Abstract

We study the structural stability of tachyonic inflation against changes in the shape of the potential. Following Lidsey,10 the concepts of rigidity and fragility are defined through a condition on the functional form of the Hubble factor. We find that the models are rigid in the sense that the attractor solutions never change as long as the conditions for inflation are met.
