Large point-degrees in intersecting families of finite vector spaces

Jicheng Ma, Hao Li

Let $V$ be an $n$-dimensional vector space over the finite field $\Fq$, and let $\Gr{V}{k}$ denote the family of all $k$-dimensional subspaces of $V$. A family \(\cF\su…

So's conjecture for integral circulant graphs of $4$ types

Hao Li, Xiaogang Liu

In [Discrete Mathematics 306 (2005) 153-158], So proposed a conjecture saying that integral circulant graphs with different connection sets have different spectra. This conjecture…

Algebraic degrees of $n$ -Cayley digraphs over abelian groups

Hao Li, Xiaogang Liu

A digraph is called an $n$ -Cayley digraph if its automorphism group has an $n$ -orbit semiregular subgroup. We determine the splitting fields of $n$ -Cayley digraphs over abelian gro…
