Özet

We define various Born-Infeld gravity theories in 3+1 dimensions which reduce to Hořava's model at the quadratic level in small curvature expansion. In their exact forms, our actions provide z→ extensions of Hořava's gravity, but when small curvature expansion is used, they reproduce finite z models, including some half-integer ones. © 2010 The American Physical Society.
