(LC) conjecture on Frobenius powers of ideals
(LC) conjecture on Frobenius powers of ideals
Let be a local or graded ring of prime characteristic , and let be an ideal, homogeneous in the graded case. Write for the ideal generated by the -th powers of elements of , and let denote zeroth local cohomology supported at . (LC) conjecture. There exists a positive integer such that
for all . Establishing this uniform linear bound on the annihilators of the zeroth local cohomology of Frobenius powers would imply, together with weak -regularity, that localizations are -regular; the conjecture is presented as an important application and its resolution is not given in the supplied text.
