Covariant constraints of massive gravity in metric formulation
Satoshi Akagi, Taisaku Mori
We propose a simple method for deriving the constraints of the de Rham-Gabadadze-Tolley model in the metric and the Lagrangian formulation, as possible as keeping the Lorentz covar…

Bottom-up approach to massive spin-two theory in arbitrary curved spacetime
Satoshi Akagi
The linear theory of massive spin-two field in arbitrary curved background is investigated. In flat spacetime, the Fierz-Pauli model is well-known as the unique linear theory descr…

Towards construction of ghost-free higher derivative gravity from bigravity
Satoshi Akagi
In this paper, the ghost-freeness of the higher derivative theory proposed by Hassan et al. in [Universe 1 (2015) 2, 92] is investigated. Hassan et al. believed the ghost-freeness…
