Alois Panholzer

摘要:

本文研究了近年来提出的树停泊函数、树停泊分布、素树停泊函数和素树停泊分布的计数问题,它们分别适用于标号有序树、标号无序树和标号二叉树等重要组合树族的根标号树.使用组合分解的基础结构的产量,求解所得方程后,隐式特征的树的大小$n$和$n$成功的驱动程序,从中我们获得准确和渐近枚举结果,这样的树停车功能的总数合适的生成函数。该方法可以扩展到一般情况下的树停车功能的大小$n$和$m<n$驱动程序,我们也能够描述的生成函数的解决方案,允许,通过应用分析组合学技术,研究的渐近行为的总数的树停车功能和分布$n \to \infty$取决于负载因子$0 < α= \frac{m}{n} < 1$。

英文摘要:

We study the enumeration problem for different kind of tree parking functions introduced recently, called tree parking functions, tree parking distributions, prime tree parking functions, and prime tree parking distributions, for rooted labelled trees of important combinatorial tree families including labelled ordered, unordered and binary trees. Using combinatorial decompositions of the underlying structures yields, after solving the resulting equations, implicit characterizations of suitable generating functions of the total number of such tree parking functions for trees of size $n$ and $n$ successful drivers, from which we obtain exact and asymptotic enumeration results. The approach can be extended to the general situation of tree parking functions for trees of size $n$ and $m<n$ drivers for which we are also able to characterize the generating functions solutions, which allow, by applying analytic combinatorics techniques, a study of the asymptotic behaviour of the total number of tree parking functions and distributions for $n \to \infty$ depending on the load factor $0 < α= \frac{m}{n} < 1$.
