Fibers of rational maps and Rees algebras of their base ideals

Tran Quang Hoa, Ho Vu Ngoc Phuong

We consider a rational map $ϕ : P_{k}^{m} ⇢ P_{k}^{n}$ that is a parameterization of an $m$ -dimensional variety. Our main goal is to study the $(m - 1)$ -dime…

The weak Lefschetz property of Gorenstein algebras of codimension three associated to the Apéry sets

Rosa M. Miró-Roig, Quang Hoa Tran

It has been conjectured that {\it all} graded Artinian Gorenstein algebras of codimension three have the weak Lefschetz property over a field of characteristic zero. In this paper,…

On the weak Lefschetz property for almost complete intersections generated by uniform powers of general linear forms

Rosa M. Miró-Roig, Quang Hoa Tran

In 2012, Migliore, the first author, and Nagel conjectured that, for all $n \geq 4$ , the artinian ideal $I = (L_{0}^{d}, \dots, L_{2 n + 1}^{d}) \subset R = k [x_{0}, \dots, x_{2 n}]$ generated by the…

The weak Lefschetz property for Artinian Gorenstein algebras of codimension three

Rosa Maria Miró-Roig, Quang Hoa Tran

We study the weak Lefschetz property of a class of graded Artinian Gorenstein algebras of codimension three associated in a natural way to the Apéry set of a numerical semigroup ge…

Fibers of rational maps and Jacobian matrices

Marc Chardin, Steven Dale Cutkosky, Quang Hoa Tran

A rational map $ϕ : P_{k}^{m} ⇢ P_{k}^{n}$ is defined by homogeneous polynomials of a common degree $d$ . We establish a linear bound in terms of $d$ for the…

Cohen-Macaulayness and canonical module of residual intersections

Marc Chardin, José Naéliton, Quang Hoa Tran

We show the Cohen-Macaulayness and describe the canonical module of residual intersections $J = a :_{R} I$ in a Cohen-Macaulay local ring $R$ , under sliding depth type h…

Bound for the number of one-dimensional fibers of a projective morphism

Quang Hoa Tran

Given a birational parameterization $ϕ : P_{k}^{2} - r i g h t a r r o w P_{k}^{3}$ of an algebraic surface $S \subset P_{k}^{3}$ , we bound the number of 1-dimensional…

Boundedness of Cohomology

Markus Brodmann, Maryam Jahangiri, Cao Huy Linh

Let $d \in N$ and let $\D^d$ denote the class of all pairs $(R, M)$ in which $R = ⨁_{n \in N_{0}} R_{n}$ is a Noetherian homogeneous ring with Artinian base ring $R_{0}$ and suc…

Castelnuovo-Mumford regularity of deficiency modules

Markus Brodmann, Maryam Jahangiri, Cao Huy Linh

Let $d \in N$ and let $M$ be a finitely generated graded module of dimension $\leq d$ over a Noetherian homogeneous ring $R$ with local Artinian base ring $R_{0}$ . Let $\beg(M)$, $\…

Uniform bounds in generalized Cohen-Macaulay rings

Cao Huy Linh, Ngo Viet Trung

We establish a uniform bound for the Castelnuovo-Mumford regularity of associated graded rings of parameter ideals in a generalized Cohen-Macaulay ring. As consequences, we obtain…
