Higher curvature gravities, unlike GR, cannot be bootstrapped from their (usual) linearizations

Deser, S. ORCID icon

Abstract

We show that higher curvature order gravities, in particular the propagating quadratic curvature models, cannot be derived by self-coupling from their linear, flat space, forms, except through an unphysical version of linearization; only GR can. Separately, we comment on an early version of the self-coupling bootstrap.
