We research the canonical remedy of classical restricted mechanical systemsformulated with a discrete time. We turn out that below very common stipulations, it ispossible to introduce nonsingular canonical differences that protect the constraintsurface and the Poisson or Dirac bracket constitution. The stipulations for thepreservation of the restrictions are extra stringent than within the non-stop case and asa outcome a few of the continuum constraints turn into moment type upon discretizationand have to be solved by means of solving their linked Lagrange multipliers.

8,a) that n = κ(LN (−D)) ≤ κ(LN ) = κ(L). 52 H. Esnault, E. 4,d). Hence we find a divisor C > 0 and µ > 0 with Lµ (−C) ample. 1) H b (X, L−1 ⊗ (L−N ·ν−µ (ν·D + C))η ) = 0 for b < n and for η sufficiently large. 13) this condition is compatible with blowing ups. Hence we may assume D + C to be a normal crossing divisor and, choosing ν large enough, we may again assume that the multiplicities of D = ν·D + C are smaller than N = N ·ν + µ. Replacing D and N by some high multiple we can assume in addition that LN (−D ) is generated by global section and that H b (X, L−N −1 (D )) = 0 for b < n.

Lemma. For an invertible sheaf L on a projective manifold X the following two conditions are equivalent: a) L is numerically effective. b) For an ample sheaf A and all ν > 0 the sheaf Lν ⊗ A is ample. Proof: By Seshadri’s criterion A is ample if and only if for some all curves C in X deg (A |C ) ≥ · m(C) > 0 and where m(C) is the maximal multiplicity of points on C. 8. Lemma. 11) and that dim X ≤ p). Then one has: §5 Vanishing theorems for invertible sheaves 47 a) κ(L) = n = dim X, if and only if c1 (L)n > 0 (where c1 (L) is the Chern class of L).

Moreover, ResDj (∇) ∈ ZZ for j = 1, . . , r. For a component Aj of A we have ResAj (∇) = 0, and for a component Bj of B we have ResBj (∇) = 1. 13). 3. Corollary. 1), assume that LN = OX (D) for a normal r crossing divisor D = j=1 αj Di with 0 < αj < N and assume that there exists an ample effective divisor B with Bred = Dred . Then H b (X, L−1 ) = 0 for b < n. 7,c). 12,d) for κ(LN (−D)) = dim X. Moreover, we may blow up, whenever we like. We can write (replacing N and D by some multiple) LN (−D) = A(Γ) for some effective divisor Γ and some ample sheaf A.
