Abstract

Generally the Brans–Dicke (BD) theory reduces to general relativity (GR) in the limit [Formula: see text] if the scalar field goes as [Formula: see text]. However, it is also known that there are examples with [Formula: see text] that does not tend to GR. We discuss another case: a homogeneous and isotropic universe filled with stiff matter. The power of time dependence of these solutions does not depend on [Formula: see text], and there is no GR limit even though we have [Formula: see text]. A perturbative and a dynamical system analysis of this exotic case are carried out.
