$P$ -polynomial weakly distance-regular digraphs

Qing Zeng, Yuefeng Yang, Kaishun Wang

A weakly distance-regular digraph is $P$ -polynomial if its attached scheme is $P$ -polynomial. In this paper, we characterize all $P$ -polynomial weakly distance-regular digraphs.

Some intersection theorems for finite sets

Mengyu Cao, Mei Lu, Benjian Lv +1

Let $n$ , $r$ , $k_{1}, \dots, k_{r}$ and $t$ be positive integers with $r \geq 2$ , and $F_{i} (1 \leq i \leq r)$ a family of $k_{i}$ -subsets of an $n$ -set $V$ . The families $\mathcal…

Cross $t$ -intersecting families for symplectic polar spaces

Tian Yao, Kaishun Wang

Let $P$ be a symplectic polar space over a finite field $F_{q}$ , and $P_{m}$ denote the collection of all $k$ -dimensional totally isotropic subspace in $\m…

Cross $t$ -intersecting families for finite affine spaces

Tian Yao, Kaishun Wang

Denote the collection of all $k$ -flats in $A G (n, F_{q})$ by $M (k, n)$ . Let $F_{1} \subset M (k_{1}, n)$ and $F_{2} \subset M (k_{2}, n)$ sati…
