Abstract

Quasi-Riemannian theories of gravity have smaller gauge groups acting on the tangent spacetime than the full Lorentz group. Among others, the spatial rotation group can be gauged to obtain spacetime asymmetric gravity with general covariance. We may introduce `spatial' higher-derivative interactions exclusively to improve ultraviolet behavior with unitarity.
