Abstract

The physical equivalence of Einstein and Jordan frames in scalar-tensor theories was explained by Dicke in 1962: they are related by a local transformation of units. We discuss this point in a cosmological framework. Our main result is the construction of a formalism in which all the physical observables are frame-invariant. The application of this approach to CMB codes is at present under analysis. © 2007 IOP Publishing Ltd.
