Spatially covariant gravity: Perturbative analysis and field transformations
Xian Gao, Chao Kang, Zhi-Bang Yao
We make a perturbative analysis of the number of degrees of freedom in a large class of metric theories respecting spatial symmetries, of which the Lagrangian includes kinetic term…

Primordial gravitational waves and perturbations during an inhomogeneous inflation
Xian Gao, Chao Kang
We investigate the inhomogeneous inflation, in which the space exponentially expands with inhomogeneities, and its cosmological perturbations. The inhomogeneous inflation is realiz…
