Coherence conjecture for multiplier ideal sheaves of Griffiths semi-positive metrics
Coherence conjecture for multiplier ideal sheaves of Griffiths semi-positive metrics
Let be a holomorphic vector bundle over an -dimensional complex manifold with a singular Hermitian metric . Let -semi-positive mean that has Griffiths semi-positive curvature. The higher rank analogue of the multiplier ideal sheaf, denoted by , is coherent.
Coherence conjecture. If is Griffiths semi-positive, then is coherent.
Coherence is known in several cases, including metrics with stronger positivity such as Nakano positivity, but the Griffiths semi-positive case is posed as the natural question because Griffiths positivity is strictly weaker than Nakano positivity.
