2) is usually called translation surface in Euclidean 3-space [E.
Let r(x, y) = (x, y, z(x, y)) be a minimal affine translation surface.
If the mean curvature H of the affine translation surface r(x, y) in [E.
The constant c = 0 means that f" = g" = 0 and the affine translation surface r(u, v) is a plane.
Let r(x, y)=(x, y, z(x, y)) be a minimal affine translation surface.

In particular Lopez  proved that the only minimal translation surfaces in hyperbolic space are totally geodesic planes.
