$M$ -离散多拟阵的可壳性
$M$-Shellability of Discrete Polymatroids
摘要:
本文证明了每个离散多拟阵都是$M$ -可壳的.这给出了,在部分情况下,一个积极的答案猜想的查里,并改善了最近的结果Schweig,他证明了$h$ -向量的格路径拟阵满足一个猜想的斯坦利。
英文摘要:
In this note we show that every discrete polymatroid is $M$-shellable. This gives, in a partial case, a positive answer to a conjecture of Chari and improves a recent result of Schweig where he proved that the $h$-vector of a lattice path matroid satisfies a conjecture of Stanley.
