Summary
We examine cosmological inflation in supergravity. We start with N = 1 supergravity with a single chiral superfield, then consider D-term inflation, with the example of the FI model. We examine possible field redefinitions. Supergravity models with slow-roll conditions satisfied are found. A special embedding of any inflationary model into supergravity is defined. The “alpha attractors” defined by Kallosh and Linde in N = 1 supergravity are defined.
