标题： Isotropisation of Generalized Scalar-Tensor theory plus a massive scalar field in the Bianchi type I model

摘要： 在本文中，我们研究了具有质量标量场的广义标量-张量理论的各向同性化。我们发现它取决于Brans-Dicke耦合函数和势能的条件，并表明渐近地，度规函数总是趋向于固有时的幂律或指数定律。这些结果推广并统一了在宇宙学常数情况下De Sitter的结果以及在指数势情况下Cooley和Kitada的结果。 显示英文摘要

摘要： In this paper we study the isotropisation of a Generalized Scalar-Tensor theory with a massive scalar field. We find it depends on a condition on the Brans-Dicke coupling function and the potential and show that asymptotically the metric functions always tend toward a power or exponential law of the proper time. These results generalise and unify these of De Sitter in the case of a cosmological constant and of Cooley and Kitada in the case of an exponential potential.
