Summary
Counting of degrees of freedom of fields up to spin 2 is described, both on-shell and off-shell. Then, the supergravity models, based on matching Bose and Fermi degrees of freedom, are inferred. The N = 1 on-shell supergravity model is defined, and the first-order and second-order formalisms, as well as the better 1.5-order formalism, in which the susy invariance of the action is shown.
