Asymptotic Lech's inequality

Craig Huneke, Linquan Ma, Pham Hung Quy +1

We explore the classical Lech's inequality relating the Hilbert--Samuel multiplicity and colength of an $m$ -primary ideal in a Noetherian local ring $(R, m)$ .…

Filter regular sequence under small perturbations

Linquan Ma, Pham Hung Quy, Ilya Smirnov

We answer affirmatively a question of Srinivas--Trivedi: in a Noetherian local ring $(R, m)$ , if $I = (f_{1}, \dots, f_{r})$ is an ideal generated by a filter-regular sequence an…

On the index of reducibility of parameter ideals: The stable and limit values

Nguyen Tu Cuong, Pham Hung Quy

Let $(R, m)$ be a Noetherian local ring and $M$ a finitely generated $R$ -module of dimension $d$ . A famous result of Northcott says that if $M$ is Cohen-Macaulay, then the in…

Upper bound of multiplicity in prime characteristic

Duong Thi Huong, Pham Hung Quy

Let $(R, m)$ be a local ring of prime characteristic $p$ of dimension $d$ with the embedding dimension $v$ . Suppose the Frobenius test exponent for parameter ideals $F t e (R)$ …
