为什么是Delannoy数?

Why Delannoy numbers?

Cyril Banderier, Sylviane Schwer

摘要:

这篇文章不是一篇研究论文,而是关于组合数学史的一个小说明:我们在这里介绍了亨利·德兰诺伊的一个尝试性的简短传记,以及他最著名的作品的调查。这回答了标题中提出的问题,因为这些作品涉及到格路径枚举,以所谓的Delannoy数,是第一个一般的方式来解决类似的问题。这些数字出现在概率对策论、DNA序列比对、瓦片问题、时间表示模型、算法分析和组合结构中。

英文摘要:

This article is not a research paper, but a little note on the history of combinatorics: We present here a tentative short biography of Henri Delannoy, and a survey of his most notable works. This answers to the question raised in the title, as these works are related to lattice paths enumeration, to the so-called Delannoy numbers, and were the first general way to solve Ballot-like problems. These numbers appear in probabilistic game theory, alignments of DNA sequences, tiling problems, temporal representation models, analysis of algorithms and combinatorial structures.
