Query: Bouncing open universes embeddable in a distorted Randall-Sundrum brane
  scenario   In reference gr-qc/0104036 a four-dimensional effective theory of gravity
embeddable in a five-dimensional "distorted" Randall-Sundrum brane scenario was
derived. The present paper is aimed at the application of such a theory to
describe physics in an open Friedmann-Robertson-Walker (Weyl-symmetric)
universe. It is shown that regular bouncing universes arise for a given range
of the free parameter of the theory.
