Abstract
The Dirac constraint formalism is applied to linearized gravity to determine the structure of constraints and construct the canonical Hamiltonian. The diffeomorphism invariance of the Lagrangian is retrieved by a nontrivial generalization of the method of Henneaux, Teitelboim and Zanelli, which takes into account the appearance of spatial derivatives of constraints in the constraint structure. A couple of first order formulations of the theory are discussed with the hope of opening avenues on an unambiguous canonical treatment of the Einstein-Hilbert action in its first order form.
