Generalized Prokhorov–Shokurov conjecture for generalized pairs
Let be a generalized sub-pair with data and , where , and are -divisors. Let be a contraction such that
Assume that is semi-ample, let be the minimum positive integer such that is basepoint-free, and assume that is generalized klt over the generic point of . Generalized Prokhorov–Shokurov conjecture. The moduli b-divisor is b-semi-ample; for the generic fiber of , there is an integer depending only on , the multiplicities of , and such that
where the representative of may be replaced within its -linear equivalence class; and is effectively b-semi-ample: there is a positive integer depending only on the dimension of , the horizontal multiplicities of , and such that is very b-semi-ample, namely for a basepoint-free divisor on some birational model of . This is proposed as a generalization of the Prokhorov–Shokurov conjecture in the setting of generalized pairs; its status is not resolved in the supplied source context.
