  (Google translate frienldly) Higher Curvature Supergravity and Cosmology by PhD Professors Sergio Ferrara, Augusto Sagnotti

  

  In this contribution we describe dual higher-derivative formulations of some cosmological models based on supergravity. Work in this direction started with the Starobinsky model, whose supersymmetric extension was derived in the late 80’s and was recently revived in view of new CMB data. Models dual to higher-derivative theories are subject to more restrictions than their…
