Vector invariant fields of finite classical groups

Yin Chen, Zhongming Tang

Let $W$ be an $n$ -dimensional vector space over a finite field $F_{q}$ of any characteristic and $mW$ denote the direct sum of $m$ copies of $W$ . Let $\mathbb{F}_q[mW]^{{\rm…

Projective dimension and regularity of edge ideal of some weighted oriented graphs

Guangjun Zhu, Li Xu, Hong Wang +1

In this paper we provide some exact formulas for the projective dimension and the regularity of edge ideals associated to vertex weighted rooted forests and oriented cycles. As som…

On Certain Monomial Sequences

Zhongming Tang

We give equivalent conditions for a monomial sequence to be a d-sequence or a proper sequence, and a sufficient condition for a monomial sequence to be an s-sequence in order to co…

Symplectic Graphs and Their Automorphisms

Zhongming Tang, Zhe-xian Wan

A new family of strongly regular graphs, called the general symplectic graphs $S p (2 ν, q)$ , associated with nonsingular alternate matrices is introduced. Their parameters as strongl…

A Matrix Approach to the Rational Invariants of Certain Classical Groups over Finite Fields of Characteristic Two

Zhongming Tang, Zhe-xian Wan

Let $F_{q}$ be a finite field of characteristic two and $F_{q} (X_{1}, ..., X_{n})$ a rational function field. We use matrix methods to obtain explicit transcendental base…

Local Homology and Local Cohomology

Zhongming Tang

Let $(R, m)$ be a local ring, $I$ a proper ideal of $R$ and $M$ a finitely generated $R$ -module of dimension $d$ . We discuss the local homology modules of $H_{I}^{d} (M)$ . When…
