摘要

We consider general scalar-tensor theories in (D +1)-dimensional spacetime. The interplay between the Jordan and Einstein frame representations is explored. As a specific illustration of the general frame-work, we examine higher-dimensional generalizations of the Jordan-Brans-Dicke theory, theories with non-minimally coupled scalar fields, f (R) gravity and low-energy string effective gravity. The properties of the Einstein frame scalar field effective potentials are discussed.
