蛛网偏序集与离散F-盒拼接

On Cobweb Posets and Discrete F-Boxes Tilings

M. Dziemianczuk

摘要:

本文利用文献[6]中定义的N^{ \infty }离散空间中的超盒F盒,对蛛网状Hasse图拼接进行了几何描述。F盒边的大小取为自然数取值序列F的各项的值。本文考虑了将图表示的超盒划分成特殊形式的块的问题,这些块被称为F-拼接。证明了容许序列F的某些子族存在这种镶嵌。我们在这里考虑的F-细分族包括F =自然数,斐波那契数,高斯整数及其相应的F-多项式(二项式,斐波那契,高斯)系数。本文提出了将这种平铺问题推广到一般情况下的多个F-范数系数上。重新制定本蛛网瓷砖问题成一个集团的问题,专门为此目的而发明的图-在这里提出了太多。为此,我们通过各种蛛网状层序家族的维恩型图来说明我们的侦察区域。

英文摘要:

F-boxes defined in [6] as hyper-boxes in N^{\infty} discrete space were applied here for the geometric description of the cobweb posetes Hasse diagrams tilings. The F-boxes edges sizes are taken to be values of terms of natural numbers' valued sequence F. The problem of partitions of hyper-boxes represented by graphs into blocks of special form is considered and these are to be called F-tilings. The proof of such tilings' existence for certain sub-family of admissible sequences F is delivered. The family of F-tilings which we consider here includes among others F = Natural numbers, Fibonacci numbers, Gaussian integers with their corresponding F-nomial (Binomial, Fibonomial, Gaussian) coefficients. Extension of this tiling problem onto the general case multi F-nomial coefficients is here proposed. Reformulation of the present cobweb tiling problem into a clique problem of a graph specially invented for that purpose - is proposed here too. To this end we illustrate the area of our reconnaissance by means of the Venn type map of various cobweb sequences families.
