Counting degree-constrained orientations

Jing Yu, Jie-Xiang Zhu

We study the enumeration of graph orientations under local degree constraints. Given a finite graph $G = (V, E)$ and a family of admissible sets $\{\mathsf P_v \subseteq \mathbb{Z}…

Maximum in-general-position set in a random subset of $F_{q}^{d}$

Yaobin Chen, Jiaxi Nie, Jing Yu +1

Let $I^\pm (F_{q}^{d}, p)$ be the maximum possible size of a point set in general position in a $p$ -random subset of $F_{q}^{d}$ . We determine the order of magnitude of $Î±(…
