Abstract For a family F of subsets define F ∖ F = { F ∖ F ′ : F , F ′ ∈ F } . The family F is called intersecting if F ∩ F ′ ≠ 0 for all F , F ′ ∈ F . We prove best possible upper bounds for | F ∖ F | in the case that F is intersecting.

关于交叉家庭中明显差异的数量

摘要 对于子集族 F 定义 F ∖ F = { F ∖ F ′ : F , F ′ ∈ F } 。如果F ∩ F ′ ≠ 0 对所有F , F ′ ∈ F ,则称F 族是相交的。我们证明了 | 的最佳可能上限 F ∖ F | 在 F 相交的情况下。
