Spatially covariant gravity: Degeneracy condition and mimetic formulation

Xuezheng Zhu

We make a perturbative analysis of spatially covariant gravity only respecting spatial symmetries, of which the Lagrangian includes the dynamic lapse function and the coupling term…

Cosmological perturbations in the spatially covariant gravity with a dynamical lapse function

Xue-Zheng Zhu, Yang Yu, Xian Gao

We investigate the scalar perturbations in a class of spatially covariant gravity theory with a dynamical lapse function. Generally, there are two scalar degrees of freedom due to…
