Abstract
A Lorentz covariant matrix regularization of membrane thories is studied.It is shown that the action for a bosonic membrane can be defined by matrix regularization in a Lorentz covariant manner. The generator of area preserving diffeomorphism can also be consistently defined by matrix regularization, and we can make the area preserving gauge symmetry manifest. However, the reparametrization BRST charge explicitly depends on a specific basis set introduced to define the matrix regularization. We also briefly comment on an extension of the present formulation to a supermembrane.
