关于极大弱分离集族的纯性
On the purity of maximal weakly separated set families
摘要:
给出了一个简短的证明,证明了在$[a,b]$之间的势的$[n]$的弱分离子集的极大族具有相同的大小。我们的证明是直接的,只使用格路径的初等组合学。
英文摘要:
We present a short proof that every maximal family of weakly separated subsets of $[n]$ of cardinality between $[a,b]$ have the same size. Our proof is direct and only uses elementary combinatorics of lattice paths.
