Reduction of maximal non-lc ideals to non--pure ideals
Reduction of maximal non-lc ideals to non--pure ideals
Let be a normal variety over a field of characteristic zero, let be an effective -divisor such that is -Cartier, and let be an ideal sheaf in . Given any model of over a finitely generated -subalgebra of , there exists a dense set of closed points of such that
for all and all .
Maximal non-lc reduction conjecture. The reduction of the maximal non-lc ideal filtration coincides with the non--pure ideal filtration on a dense set of closed fibers, as asserted above.
The conjecture is presented as the characteristic-zero/positive-characteristic analogue for maximal non-lc and non--pure ideals, and the paper proves that it follows from the weak ordinarity conjecture. The parser supplies no resolution evidence for this statement.
