摘要
本文研究了有限域上n维仿射空间的仿射线诱导的图Γ的第二次成分Γ_2(α)的代数和组合性质.利用在仿射群作用下的轨道的代表元,证明了第二次成分Γ_2(α)是连通的、正则的,但不是边正则的.
This article studies algebraic and combinatorial properties for the second subconstituentΓ2α) of the graphΓinduced by affine lines in n-dimensional affine space over finite fields.By using representation elements in orbits under the affine group,we prove that the second subconstituentΓ2α) is connected and regular,but not edge-regular.
