Li's -effective adjunction conjecture
Let be a positive integer and let be a DCC set of real numbers. A -base-point-free -divisor on a normal projective variety is one for which there exist and base-point-free -divisors such that
Let be an lc-trivial fibration with , whose horizontal coefficients belong to , and let be its moduli part. Li's conjecture. There exist a positive integer and a finite set , depending only on and , such that is -base-point-free. This is a stronger irrational-coefficient variation of the Prokhorov–Shokurov conjecture; the paper establishes the equivalence of the two effective adjunction conjectures, but the supplied text does not state that this conjecture itself is resolved.
