Generalized log nonvanishing and abundance conjecture for movable divisor cones
Generalized log nonvanishing and abundance conjecture for movable divisor cones
Let be a projective klt pair of dimension , and fix an integer with . Let be the cone generated by numerical classes of effective Cartier divisors whose stable base locus has codimension at least , and let be its closure in . Generalized log nonvanishing and abundance conjecture. If
then
This simultaneously generalizes the log nonvanishing and log abundance conjectures, corresponding to and , respectively. The source does not state a resolution status for this generalized conjecture.
