Level of Regions for Deformed Braid Arrangements

Yanru Chen, Houshan Fu, Suijie Wang +1

This paper primarily investigates a specific type of deformation of the braid arrangement $B_{n}$ in $R^{n}$ , denoted by $B_{n}^{A}$ and defined in (1.2). Let…

Level Decompositions for Symmetric Deformations of the Braid Arrangement

Yanru Chen, Suijie Wang, Jinxing Yang +1

Let $A \subseteq R_{\geq 0}$ be finite and nonempty, and let $A^{A} = (A_{1}^{A}, A_{2}^{A}, \dots)$ be the associated sequence of symmetric deformations of t…

Counting Flows of $b$ -compatible Graphs

Houshan Fu, Xiangyu Ren, Suijie Wang

Kochol introduced the assigning polynomial $F (G, α; k)$ to count nowhere-zero $(A, b)$ -flows of a graph $G$ , where $A$ is a finite Abelian group and $α$ is a ${0, 1}$ -assigning from…

Two Bijections on NBC Subsets

Houshan Fu, Baoren Peng, Suijie Wang +1

We establish two explicit bijections: from acyclic reorientations of an oriented matroid to no broken circuit (NBC) subsets of its underlying matroid, and from regions of a real hy…

Deformed Intersections of Half-spaces

Houshan Fu, Boxuan Li, Chunming Tang +1

This paper is devoted to the classification problems concerning extended deformations of convex polyhedra and real hyperplane arrangements in the following senses: combinatorial eq…
