Abstract

We perform a Hamiltonian analysis of general bimetric gravity. We determine the four first class constraints that are generators of the diagonal diffeomorphism. We further analyze the remaining constraints and we present evidence that these constraints should be second class constraints in order to have a theory with the Hamiltonian constraint as the first class constraint.
