The nucleus of the Grassmann graph $J_{q} (N, D)$

Jae-Ho Lee, Jongyook Park, Ian Seong

Let $F_{q}$ denote a finite field with $q$ elements. Let $N$ and $D$ denote integers with $N > D \geq 1$ . Let $V$ denote an $N$ -dimensional vector space over $\mathbb…

Counting edges of different types in a local graph of a Grassmann graph

Ian Seong

Let $F_{q}$ denote a finite field with $q$ elements. Let $n, k$ denote integers with $n > 2 k \geq 6$ . Let $V$ denote a vector space over $F_{q}$ that has dimension $n$ .…
