高阶引力场:协变公式中的膜运动方程

Higher order dilaton gravity: brane equations of motion in the covariant formulation

Dominika Konikowska, Marek Olechowski

摘要:

研究了具有一般膜定域相互作用的伸缩子引力。被认为是任意阶场导数的校正模型。用协变方法导出了膜上的有效引力运动方程。讨论了这种膜方程对体质量的依赖性。结果表明,大量独立膜运动方程的数量强烈依赖于模型和背景假设的对称性。两个和四个领域的衍生物的例子更详细地介绍。

英文摘要:

Dilaton gravity with general brane localized interactions is investigated. Models with corrections up to arbitrary order in field derivatives are considered. Effective gravitational equations of motion at the brane are derived in the covariant approach. Dependence of such brane equations on the bulk quantities is discussed. It is shown that the number of the bulk independent brane equations of motion depends strongly on the symmetries assumed for the model and for the background. Examples with two and four derivatives of the fields are presented in more detail.
