关于 d 进制分区及其在初等对称分区中的应用的若干思考

组合数学 2026-01-15 v2

摘要

我们证明了新的关于 pd(n)p_d(n) 的公式,即 nndd 进制分区数,同时也给出了其多项式部分的表达式。给定分区 λ=(λ1,,λ)\lambda=(\lambda_1,\ldots,\lambda_{\ell}),其关联的第 jj 项对称初等分区 prej(λ)pre_{j}(\lambda) 是由分量集合 \{\lambda_{i_1}\cdots\lambda_{i_j\;\;:\;\;1\leq i_1 < \cdots < i_j\leq \ell\}\} 构成的分区。我们证明,如果 λ\lambdaμ\mu 是两个长度为 \elldd 进制分区,且满足 prej(λ)=prej(μ)pre_j(\lambda)=pre_j(\mu)λi1λij=μi1μij\lambda_{i_1}\cdots \lambda_{i_j} = \mu_{i_1}\cdots \mu_{i_j},对于所有 1i1<<ij1\leq i_1 < \cdots < i_j\leq \ell,则 λ=μ\lambda=\mu

备注

We found a gap in the proof of Theorem 4.2, in the previous version. In order do correct it, we added a supplementary condition in the statement of Theorem 4.2; 8 pages
