A strategy for a realization of a problem free Einstein - Hilbert action along with a problem free toy cosmology

PDF Version Also Available for Download.

Description

We describe features of a low energy effective Scalar-Tensor theory of gravity having a divergent non-minimal coupling at a point where a fermionic part of the action identically vanishes and is therefore non-dynamical. Under fairly general conditions, theories having a divergent non-minimal coupling at a point can support non-topological soliton solutions. The interior of all sufficiently large solitonic domains approach a unique limit point determined by the vanishing of the effective potential of the non-minimally coupled scalar field. This can lead to a realization of an effective Einstein-Hilbert action with no cosmological constant problem. A cosmology with characteristic features follows.
