Abstract
We define various Born-Infeld gravity theories in dimensions which reduce to Hořava’s model at the quadratic level in small curvature expansion. In their exact forms, our actions provide extensions of Hořava’s gravity, but when small curvature expansion is used, they reproduce finite models, including some half-integer ones.
