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

Shuhui Yu, Lijun Ji

Let $F$ be a family of $k$ -dimensional subspaces of an $n$ -dimensional vector space. Write $\mathcal{D}_{\mathcal{F}}(H;t)=\{F\in \mathcal{F}\colon \dim(F\cap H)\leq t \}…

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

Lijun Ji, Dehai Liu, Kaishun Wang +2

Let $V$ be a finite dimensional vector space over a finite field, and $F$ a family consisting of $k$ -subspaces of $V$ . The family $F$ is called $t$ -intersecting…
