  It is shown that quantum one-loop potentials of the bulk fields in the
Randall and Sundrum (RS) model may be immediately expressed in integrals with
use of Barvinsky-Nesterov or equivalently Gelfand-Yaglom methods of calculation
of quantum determinants. Simple expression is obtained for the UV-finite
difference of one-loop quantum energies for two arbitrary values of parameter
of the double-trace asymptotic boundary condition in one-brane and two-brane
RS-models. Compact formula for Schwinger-DeWitt expansion gives values of
induced Planck mass and induced gauge coupling constant in transverse space.
S-DW expansion is plagued by IR-divergences in one-brane RS-model and makes
sense in two-brane model.
