关于划分不同部分和奇数部分

On the partitions into distinct parts and odd parts

Mircea Merca

摘要:

本文证明了当$n$为奇数时,$n$的奇数分块中的部分数与$n$的不同分块中的部分数之差满足关于分拆函数$p(n)$的欧拉递推关系.这种差异的分解在所有的分区的$n$的部件的总数也来自。在这种情况下,我们推测,对于$k>0$,系列$$ (q^2;q^2)_\infty \sum_{n=k}^\infty \frac{q^{{k\choose 2}+(k+1)n}}{(q;q)_n} \begin{bmatrix} n-1\\k-1 \end{bmatrix} $$有非负系数。

英文摘要:

In this paper, we show that the difference between the number of parts in the odd partitions of $n$ and the number of parts in the distinct partitions of $n$ satisfies Euler's recurrence relation for the partition function $p(n)$ when $n$ is odd. A decomposition of this difference in terms of the total number of parts in all the partitions of $n$ is also derived. In this context, we conjecture that for $k>0$, the series $$ (q^2;q^2)_\infty \sum_{n=k}^\infty \frac{q^{{k\choose 2}+(k+1)n}}{(q;q)_n} \begin{bmatrix} n-1\\k-1 \end{bmatrix} $$ has non-negative coefficients.
