Mengyu Cao, Benjian Lv, Kaishun Wang, Sanming Zhou

摘要:

设$V$是有限域$\mathbb{F}_q$上的$n$维向量空间.本文描述了$V$的大尺寸$k$维子空间的极大非平凡$t$ -交族的结构。我们还确定了具有最大尺寸的非平凡$t$ -相交族。在特殊情况下,当$t=1$,我们的结果产生了著名的Hilton-Milner定理的向量空间。

英文摘要:

Let $V$ be an $n$-dimensional vector space over a finite field $\mathbb{F}_q$. In this paper we describe the structure of maximal non-trivial $t$-intersecting families of $k$-dimensional subspaces of $V$ with large size. We also determine the non-trivial $t$-intersecting families with maximum size. In the special case when $t=1$ our result gives rise to the well-known Hilton-Milner Theorem for vector spaces.
