And from metric perturbations around the RS background with a single brane embedded, we also show that for a vanishing Gauss-Bonnet coefficient, the brane bending allows us to reproduce the 4D Einstein gravity at the linearized level.9 pages with no figures, Proceeding of the talk at COSMO-2000, Cheju Island, Korea, Sep. 4-8, 2000; acknowledgement addedHigh Energy Physics - Theorytext
