Supersymmetry of higher-derivative supergravity in AdS4 holography

An action for the higher-derivative corrections to minimal gauged Euclidean supergravity in four dimensions has been recently proposed. We demonstrate that the supersymmetrie solutions of this model are those of the two-derivative action, and investigate some of their properties. In particular, we prove a formula for the renormalized on-shell action in terms of contributions from fixed points of a U(1) action, and confirm that it is invariant under deformations which preserve the boundary almost contact structure.
