零件尺寸不超过k的可拆卸组合物

Integer compositions with part sizes not exceeding k

Martin E. Malandro

摘要:

我们研究了整数n的部分大小不超过一个固定整数k的合成。我们使用分析组合学的方法来获得精确的渐近公式的数量这样的组合物,在所有这样的组合物中的部件的总数,在这样的组合物中的部件的预期数量,在所有这样的组合物中出现的特定部件尺寸的总次数,以及在这样的组合物中给定部件尺寸的预期多重性。在此过程中,我们还获得了递归和生成函数,用于计算其中的几个量。我们的研究结果也适用于某些类型的平铺和节奏模式的问题。

英文摘要:

We study the compositions of an integer n whose part sizes do not exceed a fixed integer k. We use the methods of analytic combinatorics to obtain precise asymptotic formulas for the number of such compositions, the total number of parts among all such compositions, the expected number of parts in such a composition, the total number of times a particular part size appears among all such compositions, and the expected multiplicity of a given part size in such a composition. Along the way we also obtain recurrences and generating functions for calculating several of these quantities. Our results also apply to questions about certain kinds of tilings and rhythm patterns.
