β¦ Synopsis
We give general bounds for the reduction numbers of ideals in arbitrary Noetherian rings and multiplicity-dependent bounds for m-primary ideals in a Noetherian local ring (R, m). In the case of polynomial rings over fields the bound is a non-elementary function with four levels of exponentiation; for primary ideals the bound is linear in the Samuel multiplicity of the ideal. Finally we extend these techniques to generic complete intersections of dimension one.

The aim of this paper is to study the relationship between the reduction number and Borel-fixed ideals in all characteristics. Especially it is shown that r(R/I ) r(R/I lex ), where I lex denotes the unique lex-segment ideal whose Hilbert function is equal to that of I . This solves a recent questio
Componentwise linear ideals were introduced earlier to generalize the result that the Stanley Reisner ideal I 2 of a simplicial complex 2 has a linear resolution if and only if its Alexander dual 2\* is Cohen Macaulay. It turns out that I 2 is componentwise linear if and only if 2\* is sequentially
