4. DE RHAM-WITT FOR LOG SCHEMESα : L → k : a fine log str. on s = Spec(k)W n (L) : Teichmüller lifting of L to W n (s) :W n (L) = L ⊕ Ker(W n (k) ∗ → k ∗ )L → W n (k) : a ↦→ [α(a)]Example : L = (N → k, 1 ↦→ 0) a (st<strong>and</strong>ard log point)W n (L) = (N → W n (k), 1 → 0) a 46
(X, M)/(s, L) : fine log scheme, log smooth <strong>and</strong> Cartiertype /(s, L)Cartier type (= integral, relative Frobenius exact)ensures the existence of Cartier isomorphism :C −1 : Ω q (X,M) ′ /(s,L)∼−→ F ∗ H q (Ω·(X,M)/(s,L) )(F : (X, M) → ((X, M) ′ = (s, L) × (s,L) (X, M) relativeFrobenius) ,C −1 : a ↦→ F ∗ a, dlog b ↦→ dlog b47
