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…

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…
