Krystian Gajdzica

摘要:

设$\mathcal{A}=(a_n)_{n\in\mathbb{N}_+}$为正整数序列。令$p_\mathcal{A}(n,k)$表示在$\{a_1,\ldots,a_k\}$中将$n$划分为部分的多色分区的数目。我们研究了任意固定整数$m\geqslant2$的序列$(p_\mathcal{A}(n,k) \pmod{m})_{n\in\mathbb{N}}$的几个算术性质。我们调查的序列的周期性和上下界的密度的集合$\{n\in\mathbb{N}: p_\mathcal{A}(n,k) \equiv i \pmod{m}\}$为一个固定的正整数$k$和$i\in\{0,1,\ldots, m-1\}$。特别是,我们将我们的结果应用到序列$\mathcal{A}$的特殊情况。此外,我们提出了一些有关限制$m$ -ary划分的结果。

英文摘要:

Let $\mathcal{A}=(a_n)_{n\in\mathbb{N}_+}$ be a sequence of positive integers. Let $p_\mathcal{A}(n,k)$ denote the number of multi-color partitions of $n$ into parts in $\{a_1,\ldots,a_k\}$. We examine several arithmetic properties of the sequence $(p_\mathcal{A}(n,k) \pmod{m})_{n\in\mathbb{N}}$ for an arbitrary fixed integer $m\geqslant2$. We investigate periodicity of the sequence and lower and upper bounds for the density of the set $\{n\in\mathbb{N}: p_\mathcal{A}(n,k) \equiv i \pmod{m}\}$ for a fixed positive integer $k$ and $i\in\{0,1,\ldots, m-1\}$. In particular, we apply our results to the special cases of the sequence $\mathcal{A}$. Furthermore, we present some results related to restricted $m$-ary partitions.
