“…One remarks that the above definition can easily be generalized to associate currents of any bidimension (k, k), 1 ≤ k ≤ m to f : C m → X. But doing this, one loses for k = 1 the closedness property as discussed in [7] and recently in [3]. Moreover, for our problem, Green-Griffiths' philosophy suggests that the geometry of these holomorphic maps should be determined by a line bundle, K X .…”
