then the set of solutions of (1.1) lies in the union of finitely many proper linear subspaces of P. We give an equivalent formulation on which we shall focus in this paper. Let {l0, . . . , lN} be the union of the sets {l0v, . . . , lnv} (v ∈ S). Define the map φ : P → P by y 7→ ( l0(y) : · · · : lN(y) ) . Put X := φ(P); then X is a linear subvariety of P of dimension n defined over K. Write xi = li(y) (i = 0, . . . , N), x = (x0 : · · · : xN) = φ(y). For v ∈ S, let Iv be the set of indices given by {li : i ∈ Iv} = {l0v, . . . , lnv}, put civ := djv if li = ljv and civ = 0 if i 6∈ Iv. Then (apart from some modifications in the norms and the height) we can rewrite (1.1) as
