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…

$k$ -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…

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…
