Description
Analytic solutions of the field equations of scalar-tensor gravity can look very different in different conformal frame representations. For example, certain Brans class IV solutions describing wormholes in the Jordan frame correspond to horizonless geometries in the Einstein frame. The reasons for such a change of behaviour under conformal mappings are elucidated in general.
