Extremal cross $t$ -intersecting families under $t$ -covering number constraints for vector spaces

Yu Zhu, Benjian Lv, Kaishun Wang

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…

On extremal cross $t$ -intersecting families with $t$ -covering number conditions

Yu Zhu, Benjian Lv, Kaishun Wang

Let $n$ , $k$ and $t$ be positive integers, and let $F$ be a collection of $k$ -subsets of $[n] = {1, 2, \dots, n}$ . The $t$ -covering number $I ¨ _{t} (F)$ of $\mathcal{F…
