给定一个Rdof维为e的仿射子空间集合R,其交图G的每个子空间都有一个顶点,并且两个顶点在G中相邻当且仅当它们对应的子空间相交。对于每对正整数d和e,我们得到了(d,e)-子空间交图类。我们根据包含度对(d,e)-子空间交图进行分类,其中e=1或e=d−1或d≤4。
Given a set R of affine subspaces in Rdof dimension e, its intersection graph G has a vertex for each subspace, and two vertices are adjacent in G if and only if their corresponding subspaces intersect. For each pair of positive integers d and e we obtain the class of (d,e)-subspace intersection graphs. We classify the classes of (d,e)-subspace intersection graphs by containment, for e=1 or e=d−1 or d≤4.
