We study graphs coming from quadratic spaces over finite fields which generalize a recent result given by Bishnoi, Ihringer, and Pepe (2020). More precisely, we study the graph defined as follows: the vertex set is the set of k-dimensional quadratic subspaces of a fixed quadratic space isometrically isomorphic to . Here λ is a non-square in , and two vertices are adjacent if .

与有限域上k平面正交集合相关的图
我们研究来自有限域上的二次空间的图,这些图概括了 Bishnoi、Ihringer 和 Pepe(2020)给出的最近结果。更准确地说,我们研究图形定义如下:顶点集是一个固定二次空间的k维二次子空间的集合 等距同构 . 这里λ是一个非平方, 和两个顶点 相邻,如果 .
