Covariant field equations of chiral N = 2 D = 10 supergravity

Even though chiral N = 2 D = 10 supergravity does not have a manifestly Lorentz-invariant action principle, it does have covariant field equations. The latter are obtained by first deriving the local supersymmetry transformations of the fields and then deducing the set of field equations that transform into one another and are required for closure of the algebra. One of the equations is the self-duality of a supercovariant fifth-rank field strength tensor. An SU(1,1) symmetry plays a crucial role in the analysis
