Minimally modified gravity with auxiliary constraints formalism
Zhi-Bang Yao, Michele Oliosi, Xian Gao +1
We investigate the possibility of reducing the number of degrees of freedom (d.o.f.) starting from generic metric theories of gravity by introducing multiple auxiliary constraints…
Minimally modified gravity with an auxiliary constraint: a Hamiltonian construction
Zhi-Bang Yao, Michele Oliosi, Xian Gao +1
Working directly with a general Hamiltonian for the spacetime metric with the decomposition and keeping only the spatial covariance, we investigate the possibility of reducin…
Spatially covariant gravity theories with two tensorial degrees of freedom: the formalism
Xian Gao, Zhi-Bang Yao
Within the general framework of spatially covariant theories of gravity, we study the conditions for having only the two tensorial degrees of freedom. Generally, there are three de…
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…
Spatially covariant gravity with velocity of the lapse function: the Hamiltonian analysis
Xian Gao, Zhi-Bang Yao
We investigate a large class of gravity theories that respect spatial covariance, and involve kinetic terms for both the spatial metric and the lapse function. Generally such kind…
