Abstract

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.

广义引力标量张量理论中的有效势

我们考虑（D +1）维时空中的一般标量张量理论。约旦和爱因斯坦框架表示之间的相互作用进行了探讨。作为一般框架的具体说明，我们研究了Jordan-Brans-Dicke理论、非最小耦合标量场理论、f (R)引力和低能弦有效引力的高维推广。讨论了爱因斯坦系标量场有效势的性质。

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
