W Goddard,DJ Kleitman - 《Discrete Mathematics》 被引量: 4发表: 2009年 The r -central factorial numbers with even indices In this paper, we introduce the r-central factorial numbers with even indices of the first and second kind as extended versions of the central factorial nu... Shiha, ...
Finally, we show the continued fraction expression of the generating function of the cyclic derangement polynomials.doi:10.1016/j.disc.2020.112109Lily Li LiuMengmeng DongDiscrete Mathematics
Two known identities can be recovered. We provide a combinatorial interpretation for the new identity and a representation of the derangement numbers in terms of the determinants of Hessenberg matrices.Zhibin Duda Fonseca, Carlos M.Applicable Analysis & Discrete Mathematics...
The spiral property implies that the polynomial is unimodal and the maximum coefficient appears exactly in the middle, which confirms a conjecture of Chen and Rota.Xiang-De ZhangDepartment of Automatic ControlNortheastern UniversityDiscrete Mathematics...
Discrete Mathematics Combinatorics Permutations DerangementDownload Wolfram Notebook A derangement is a permutation in which none of the objects appear in their "natural" (i.e., ordered) place. For example, the only derangements of are and , so . Similarly, the derangements of are , , , , ,...
