Modular Ideals and Factorizations of Affine Hyperplane Arrangements

Yanru Chen, Weikang Liang, Suijie Wang +1

Let $A$ be an affine hyperplane arrangement, let $L (A)$ be its intersection semilattice, and let $χ_{A} (t)$ be its characteristic polynomial. We intro…

Characterizing Nice Partition of Graphical Arrangements

Weikang Liang, Suijie Wang, Chengdong Zhao

The successive works of Terao as well as Stanley revealed that, for graphical arrangements, supersolvability and the existence of nice partitions are equivalent properties, both ch…

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…

$k$ -Adjoint of Hyperplane Arrangements

Weikang Liang, Suijie Wang, Chengdong Zhao

In this paper, we introduce the $k$ -adjoint of a given hyperplane arrangement $A$ associated with rank- $k$ elements in the intersection lattice $L (A)$ , which ge…
