“…Les conjectures C orb n,m (voir la conjecture 7.1 ci-dessous) et la conjecture 6.82 (1)-(2) ci-dessus sont déduites de conjectures (plus ou moins) standard du LMMP dans [17]. La conjecture d'isotrivialité la conjecture 13.29 sur les familles de variétés canoniquement polarisées y est aussi déduite des conjectures C orb n,m et la conjecture 6.82.…”

“…Starting from our initial log-canonical (X, ∆), we can thus take a logresolution g : X → X such that X is smooth, and a smooth orbifold pair (X , ∆ ) with f : X → Z holomorphic and birationally equivalent to f via a modification v : Z → Z, Z smooth, such that: g * (∆ ) = ∆, K X + ∆ = g * (K X + ∆) + E, with E g-exceptional, and such that, moreover, f : X → Z is ∆ -neat. Because our curves C = g * (C ), with C ⊂ Y a Mehta-Ramanathan curve for H = π * (B) do not meet the (6) And since (X, ∆) is log-canonical. This the place where this hypothesis is used.…”

“…In the classification of varieties proposed by Campana [6,7], a central rôle is played by the concept of general type fibrations. Roughly speaking, a fibration f : X −→ Y is of general type if either Y is of general type, or f has "enough multiple fibres" (Definition 1.2).…”
