On simple bootstrap in metric gravity
arXiv:2104.06140
Abstract
The simplest approach to bootstrap in general relativity is considered. The approach claimed to recover the infinite perturbative series of graviton interaction terms with a recursive coupling metric perturbations to their energy-momentum tensor. We show that the approach provides an incorrect expression for three-graviton interaction term. Other difficulties related with the bootstrap approach are discussed.
