Hilton-Milner theorem for $k$ -multisets

Jiaqi Liao, Zequn Lv, Mengyu Cao +1

Let $k, n \in N^{+}$ and $m \in N^{+} \cup {\infty}$ . A $k$ -multiset in $[n]_{m}$ is a $k$ -set whose elements are integers from ${1, 2, \dots, n}$ , an…

Erdős-Ko-Rado Theorem for Bounded Multisets

Jiaqi Liao, Zequn Lv, Mengyu Cao +1

Let $k, m, n$ be positive integers with $k \geq 2$ . A $k$ -multiset of $[n]_{m}$ is a collection of $k$ integers from the set ${1, 2, \dots, n}$ in which the integers c…

Triangles in r-wise t-intersecting families

Jiaqi Liao, Mengyu Cao, Mei Lu

Let $t$ , $r$ , $k$ and $n$ be positive integers and $F$ a family of $k$ -subsets of an $n$ -set $V$ . The family $ \CF $ is $r$ -wise $t$ -intersecting if for any $ F_1, \l…

Edge pancyclic derangement graphs

Zequn Lv, Mengyu Cao, Mei Lu

We consider the derangement graph in which the vertices are permutations of ${1, \dots, n}$ . Two vertices are joined by an edge if the corresponding permutations differ in every…

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…

$r$ -cross $t$ -intersecting families for vector spaces

Mengyu Cao, Mei Lu, Benjian Lv +1

Let $V$ be an $n$ -dimensional vector space over the finite field $F_{q}$ , and $[k V]$ denote the family of all $k$ -dimensional subspaces of $V$ . The families $\mathcal…
