Abstract
The finite-element approach described in a previous paper approximates the operator Dirac equation on a lattice in such a way that the equal-time anticommutation relations are exactly maintained. Moreover, the approximation preserves unitarity (and chiral invariance in the massless theory) and there is no fermion doubling.Keywords
