DESCRIPTION:In this talk we describe dual higher derivative formulations o
 f some cosmological models based on supergravity. Work in this direction s
 tarted with the R + R2 Starobinsky model\, whose supersymmetric extension 
 was derived in the late 80s and was recently revived in view of new CMB da
 ta. Models dual to higher-derivative theories are subject to more restrict
 ions than their bosonic counterparts or standard supergravity duals. We wi
 ll start with a brief description of R + R2 supergravity\, then  a scale i
 nvariant R2 Supergravity and finally  theories with a nilpotent curvature\
 , whose duals describe non-linear realizations (in the form a Volkov-Akulo
 v constrained superfield) coupled to supergravity.\n\nhttps://indico.ific.
