In this paper we present a very simple and independent argument for the absence of the Boulware-Deser ghost in the recently proposed potentially ghost-free non-linear massive gravity. The limitation is that, in its simple form, the argument is, in a sense, non-constructive and less explicit than the standard approach. However, the formalism developed here may prove to be useful for discussing the formal aspects of the theory.

A new look at multi-gravity and dimensional deconstruction
Keeping the lapse free in deconstruction yields scalar-tensor multi-gravity, which reproduces 5D Randall-Sundrum brane cosmology equations in the continuum limit.

Non-primary square roots in massive gravity
Non-primary square roots in massive gravity theories are generally covariant, but lack analytic perturbation theory in the elementary symmetric polynomials of the Lagrangian.
