Strong liftability conjecture for cyclic covers over smooth projective toric varieties
Strong liftability conjecture for cyclic covers over smooth projective toric varieties
Let be a smooth projective toric variety, and let be an invertible sheaf on . Let be a positive integer prime to , and let be an effective divisor on such that
and . Let be the cyclic cover obtained by taking the -th root out of .
Strong liftability conjecture. The scheme is a smooth projective scheme which is strongly liftable over .
This conjecture proposes that the strong liftability result known for cyclic covers of projective spaces extends to cyclic covers over all smooth projective toric varieties. Ordinary liftability in this setting has already been proved, but strong liftability remains open in the supplied source.
