$d$ -Degree Erdős-Ko-Rado theorem for finite vector spaces

Yunjing Shan, Junling Zhou

Let $V$ be an $n$ -dimensional vector space over the finite field $F_{q}$ and let $[k V]_{q}$ denote the family of all $k$ -dimensional subspaces of $V$ . A fam…

On cover-free families of finite vector spaces

Yunjing Shan, Junling Zhou

There is a large literature on cover-free families of finite sets, because of their many applications in combinatorial group testing, cryptographic and communications. This work st…

Suboptimal $s$ -union familes and $s$ -union antichains for vector spaces

Yunjing Shan, Junling Zhou

Let $V$ be an $n$ -dimensional vector space over the finite field $F_{q}$ , and let $L (V) = ⋃_{0 \leq k \leq n} [k V]$ be the set of all subspaces…
