P. Fré and A.S. Sorin Inflation and integrable one-field cosmologies embedded in rheonomic supergravity Fortschritte der Physik 62
It is shown that the new approach to the embedding of the inflationary potentials into supergravity, presented in a quite recent paper  of Ferrara, Kallosh, Linde and Porrati can be formulated within the framework of standard matter coupled supergravity, without the use of the new minimal auxiliary set and of conformal compensators. The only condition is the existence of a translational Peccei Quinn isometry of the scalar Kähler manifold. The authors suggest that this embedding strategy based on a nilpotent gauging amounts to a profound Copernican Revolution.
