Query: Generalized massive gravity in arbitrary dimensions and its Hamiltonian
  formulation   We extend the four-dimensional de Rham-Gabadadze-Tolley (dRGT) massive
gravity model to a general scalar massive-tensor theory in arbitrary
dimensions, coupling a dRGT massive graviton to multiple scalars and allowing
for generic kinetic and mass matrix mixing between the massive graviton and the
scalars, and derive its Hamiltonian formulation and associated constraint
system. When passing to the Hamiltonian formulation, two different sectors
arise: a general sector and a special sector. Although obtained via different
ways, there are two second class constraints in either of the two sectors,
eliminating the BD ghost. However, for the special sector, there are still
ghost instabilities except for the case of two dimensions. In particular, for
the special sector with one scalar, there is a "second BD ghost".
