超越爱因斯坦:引力的多项式仿射模型

Beyond Einstein: A Polynomial Affine Model of Gravity

Oscar Castillo-Felisola

摘要:

我们表明,最近制定的多项式仿射引力模型的有效场方程,在一个无扭连接的部门,接受一般爱因斯坦流形-有或没有宇宙学常数-作为解决方案。此外,有效场方程部分是从杨-米尔斯引力理论(Stephenson-Kilmister-Yang,SKY)得到的。此外,我们发现一个最低限度的耦合无质量标量场在广义相对论在一个“最低限度”耦合标量场在这个仿射模型的推广。最后,我们提出了路线图,以找到通用的解决方案,有效场方程与各向同性或宇宙(即,均匀和各向同性)对称。

英文摘要:

We show that the effective field equations for a recently formulated polynomial affine model of gravity, in the sector of a torsion-free connection, accept general Einstein manifolds---with or without cosmological constant---as solutions. Moreover, the effective field equations are partially those obtained from a gravitational Yang-Mills theory known as the Stephenson-Kilmister-Yang (SKY) theory. Additionally, we find a generalisation of a minimally coupled massless scalar field in general relativity within a "minimally" coupled scalar field in this affine model. Finally, we present the road map to finding general solutions to the effective field equations with either isotropic or cosmologic (i.e., homogeneous and isotropic) symmetry.
