Fujino's injectivity conjecture for log-canonical pairs
Let be a compact Kähler manifold and be a simple-normal-crossing (snc) divisor on . Let be a semi-positive line bundle on , meaning that it admits a smooth Hermitian metric with
Let be a section whose zero locus contains no log-canonical centers of , namely no connected component of a nonempty intersection of irreducible components of . Fujino's injectivity conjecture. The multiplication map induced by tensoring with
is injective for every . This conjecture has been fully solved by Junyan Cao and Mihai Păun.
