Query: Radion stability and induced, on-brane geometries in an effective
  scalar-tensor theory of gravity   About a decade ago, using a specific expansion scheme, effective, on-brane
scalar tensor theories of gravity were proposed by Kanno and Soda (Phys.Rev.
{\bf D 66} 083506 ,(2002)) in the context of the warped two brane model of
Randall--Sundrum. The inter-related effective theories on both the branes were
derived with the space-time dependent radion field playing a crucial role.
Taking a re-look at this effective theory, we find cosmological and spherically
symmetric, static solutions sourced by a radion--induced, effective stress
energy, as well as additional, on-brane matter. The distance between the branes
(governed by the time or space dependent radion) is shown to be stable and
asymptotically non-zero, thereby setting aside any possibility of brane
collisions. It turns out that the inclusion of on-brane matter plays a decisive
role in stabilising the radion - a fact which we demonstrate through our
solutions.
