Abstract
Abstract: Let a be a proper ideal of a commutative Noetherian ring R of prime characteristic p and let Q(a) be the smallest positive integer m such that (aF)[pm]=a[pm], where aF is the Frobenius closure of a. This paper is concerned with the question whether the set {Q(a[pm]):m∈N0} is bounded. We give an affirmative answer in the case that the ideal a is generated by an u.s.d-sequence c1,…,cn for R such that (i) the map R/∑nj=1Rcj→R/∑nj=1Rc2j induced by multiplication by c1…cn is an R-monomorphism; (ii) for all p∈ass(cj1,…,cjn), c1/1,…,cn/1 is a pRp-filter regular sequence for Rp for j∈{1,2}.
