Localization of Gravity on Dilatonic Domain Walls: Addendum to ``Solitons in Brane Worlds''

We supplement the discussion on localization of gravity on dilatonic domain walls in ``Solitons in Brane Worlds’’ (Nucl. Phys. B576, 106, hep-th/9911218) by giving unified and coherent discussion which combines the result of this paper and the expanded results in the author’s subsequent papers in an attempt to avoid misleading readers. We also discuss the possible string theory embeddings of the Randall-Sundrum type brane world scenarios through non-dilatonic and dilatonic domain walls, which straightforwardly follows from the author’s previous works but was not elaborated explicitly.
