Various Modified Solutions of the Randall-Sundrum Model with the   Gauss-Bonnet Interaction
  The Gauss-Bonnet interaction is the only consistent quadratic interaction below the Planck scale in the Randall-Sundrum compactification. We study various static and inflationary solutions including this Gauss-Bonnet interaction.
