One-element Extensions of Hyperplane Arrangements

Hang Cai, Houshan Fu, Suijie Wang

We classify one-element extensions of a hyperplane arrangement by the induced adjoint arrangement. Based on the classification, several kinds of combinatorial invariants including…

Adjoints of Matroids

Houshan Fu, Chunming Tang, Suijie Wang

We show that an adjoint of a loopless matroid is connected if and only if it itself is connected. Our first goal is to study the adjoint of modular matroids. We prove that a modula…

Bijections on $r$ -Shi and $r$ -Catalan Arrangements

Houshan Fu, Suijie Wang, Weijin Zhu

Associated with the $r$ -Shi arrangement and $r$ -Catalan arrangement in $R^{n}$ , we introduce a cubic matrix for each region to establish two bijections in a uniform way. Firstl…

Pattern Avoidance of Generalized Permutations

Zhousheng Mei, Suijie Wang

In this paper, we study pattern avoidances of generalized permutations and show that the number of all generalized permutations avoiding $π$ is independent of the choice of $π\in S…

Parallel Translates of Represented Matroids

Beifang Chen, Houshan Fu, Suijie Wang

Given an $F$ -represented matroid $(M, ρ)$ with the ground set $[m]$ , the representation $ρ$ naturally defines a hyperplane arrangement $A_{ρ}$ . We will study its paral…

Order Preserving Maps of Posets

Zhousheng Mei, Suijie Wang

For any two finite posets $P$ and $Q$ , let $\Hom(P,Q)$ be the hom-poset consisting of all order preserving maps from $P$ to $Q$ , and $J (Q)$ the collection of all order ideals of $Q…

Orbits of antichains in certain root posets

Chao-Ping Dong, Suijie Wang

This paper gives another proof of Propp and Roby's theorem saying that the average antichain size in any reverse operator orbit of the poset $[m] \times [n]$ is $\frac{mn}{m + n}$ . It…

Mobius Conjugation and Convolution Formulae

Suijie Wang

Let $P$ be a locally finite poset with the interval space $\Int(P)$, and $R$ a ring with identity. We shall introduce the Möbius conjugation $μ^{*}$ sending each function $f:P\to…

Bounds on Characteristic Polynomials

Suijie Wang, Yeong-Nan Yeh, Fengwei Zhou

Suppose $G$ is a simple graph with $n$ vertices, $m$ edges, and rank $r$ . Let $χ_{G} (t) = a_{0} t^{n} - a_{1} t^{n - 1} + \dots + (- 1)^{r} a_{r} t^{n - r}$ be the chromatic polynomial of $G$ . For $q,k\in \B…

Laplacian spectral characterization of some graph products

Suijie Wang, Xiaogang Liu

This paper studies the Laplacian spectral characterization of some graph products. We consider a class of connected graphs: $G = G : ∣ E G ∣ \leq ∣ V G ∣ + 1$ , and characterize all…
