Abstract
Lemma 8.2. Assume Theorems 5.56, 5.57, 5.58, 5.59, 5.60 in dimensions ≤ n - 1. Let β W X → U be a projective morphism of normal quasi-projective varieties. Let (X; Δ + C = S + A +B +C) be a ℚ-factorial dlt pair with S = ⌊Δ⌋, such that KX + Δ +C is nef over U and B+A/U) contains no non-klt centers of (X,Δ + C). Let Φi: Xi → Xi+1 be a sequence of flips and divisorial contractions over U for the (KX + Δ)-mmp over U with scaling of C.
