Card deals, lattice paths, abelian words and combinatorial identities

David Callan

摘要:

我们给出组合解释的几个相关的身份与名称Barrucand,Strehl和Franel,其中包括一个的Aesthetic号码。采用的组合结构是乱序型卡交易介绍了在以前的论文Barrucand的身份,标记格路径,并在评论杰弗里Shallit,阿贝尔词超过3个字母的字母表。

英文摘要:

We give combinatorial interpretations of several related identities associated with the names Barrucand, Strehl and Franel, including one for the Apery numbers. The combinatorial constructs employed are derangement-type card deals as introduced in a previous paper on Barrucand's identity, labeled lattice paths and, following a comment of Jeffrey Shallit, abelian words over a 3-letter alphabet.
