$s$-almost cross-$t$-intersecting families for vector spaces

Dehai Liu, Jinhua Wang, Tian Yao

Let $V$ be an $n$-dimensional vector space over the finite field ${\mathbb{F}}_q$, and $\left[\genfrac{}{}{0ex}{}{V}{k}\right]$ denote the family of all $k$-dimensional subspaces of $V$. The families $\mat…
