新质量引力的Born-Infeld延拓

Born-Infeld extension of new massive gravity

Ibrahim Gullu, Tahsin Cagri Sisman, Bayram Tekin

摘要:

我们提出了一个三维引力Born-Infeld理论,它在小曲率展开的二次水平上还原为最近发现的新大质量引力(NMG),并在三次水平上再现了从AdS/CFT获得的NMG变形。我们的行动提供了一个显着的扩展NMG的所有订单的曲率,并可能定义一个一致的量子引力。

英文摘要:

We present a three-dimensional gravitational Born-Infeld theory which reduces to the recently found New Massive Gravity (NMG) at the quadratic level in the small curvature expansion and at the cubic order reproduces the deformation of NMG obtained from AdS/CFT. Our action provides a remarkable extension of NMG to all orders in the curvature, and might define a consistent quantum gravity.
