Regularity of quasi-symbolic and bracket powers of Borel type ideals

open access: yes, 2014
In this paper, we show that the regularity of the q-th quasi-symbolic power $I^{((q))}$ and the regularity of the $q$-th bracket power $I^{[q]}$ of a monomial ideal of Borel type $I$, satisfy the relations $reg(I^{((q))})\leq q \cdot reg(I ...

A generalization of Croot-Lev-Pach's Lemma and a new upper bound for the size of difference sets in polynomial rings

open access: yes, 2018
Croot, Lev and Pach used a new polynomial technique to give a new exponential upper bound for the size of three-term progression-free subsets in the groups $(\mathbb Z _4)^n$.

Polynomial Retracts and the Jacobian Conjecture

open access: yes, 1997
Let $ K[x, y]$ be the polynomial algebra in two variables over a field $K$ of characteristic $0$. A subalgebra $R$ of $K[x, y]$ is called a retract if there is an idempotent homomorphism (a {\it retraction}, or {\it projection}) $\varphi: K[x, y] \to K[x,

On the Stanley depth of edge ideals of line and cyclic graphs

open access: yes, 2015
We prove that the edge ideals of line and cyclic graphs and their quotient rings satisfy the Stanley conjecture. We compute the Stanley depth for the quotient ring of the edge ideal associated to a cycle graph of length $n$, given a precise formula for ...
