摘要：
We investigate the dynamical equivalence of the varying G and ? cosmology with the Brans-Dicke theory. We show that there exist a point transformation which connects the field equations for a spatially flat FLRW geometry. We conclude that the two theories share the same integrability properties and solution trajectories.
