How (not) to use the Palatini formulation of scalar-tensor gravity
PHYSICAL REVIEW D, no. 10 (2007)
Abstract
We revisit the problem of defining nonminimal gravity in the first order formalism. Specializing to scalar-tensor theories, which may be disguised as "higher-derivative" models with the gravitational Lagrangians that depend only on the Ricci scalar, we show how to recast these theories as Palatini-like gravities. The correct formulation u...More
