The ordinarity conjecture for smooth projective schemes
The ordinarity conjecture for smooth projective schemes
Let be a smooth projective scheme defined over a field of characteristic zero. After spreading out , for a prime , write for its reduction modulo , and let denote the sheaf of exact differential -forms on . Ordinarity conjecture. For infinitely many primes , the reduction is ordinary in the sense of Bloch–Kato, namely
for all . This conjecture is used to obtain the implication from -Du Bois singularities to --injectivity in reductions modulo infinitely many primes; its general status is not resolved in the source.
