Effective adjunction conjecture for lc-trivial fibrations
Effective adjunction conjecture for lc-trivial fibrations
Let be an lc pair such that is a -Cartier divisor, and let be an lc-trivial fibration. Let denote its moduli b-divisor. Effective adjunction conjecture. There exists a positive integer , depending only on the dimension of and the horizontal multiplicities of , such that is a base-point free b-divisor. This is a conjecture about effectivity in the canonical bundle formula; the paper studies a variant suitable for induction and real coefficients, while the general assertion is not stated as resolved here.
