Translation Surfaces with Zero Mean Curvature in (2+p)-Dimensional Pseudo-Euclidean Space E_2^(2+p) or E_p^(2+p)

Let Ep^2＋p（resp.E2^2＋p） be a （2＋p）-dimensional pseudo-Euclidean space with the index p （resp.2）. The maximal spacelike or minimal timelike translation surfaces M^2 in Ep^2＋p or E2^2＋p are considered and a complete classification is given.
