COVARIANT QUANTIZATION OF D-BRANES

We have found that kappa symmetry allows covariant quantization provid ed the ground state of the theory is strictly massive. For D-p-branes a Hamiltonian analysis is performed to explain the existence of a mani festly supersymmetric and Lorentz covariant description of the BPS sta tes of the theory. The covariant quantization of the D-0-brane is pres ented as an example.
