预制偏序集Whitney数的初步观察
First Observations on Prefab Posets Whitney Numbers
摘要：
本文在作者最近构造的蛛网预制集的结构自然有限子集中引入了自然偏序。然后计算了构成类Stirling数三角阵的第二类子集的Whitney数，并给出了它们的显式表达式。其次，在第二种构造中，我们赋予预构式的集合和以另一种偏序，使它们的类Bell数包含Fibonacci三元组序列，以便将著名的二项式Newton系数与斐波那契数之间的关系推广到它们的亲属的无穷大，其中也包含Fibonacci三元组序列和类二项式系数（包括关联系数）。第一个偏序是F序列无关的，第二个偏序是F序列依赖的，其中F是所谓的通过构造确定蛛网偏序集的容许序列。如果序列F恰好是Fibonacci序列，则F确定的蛛网偏序集Hasse图成为被特定蛛网覆盖的Fibonacci树。从形式级数的线性代数的观点来看，这些是量子物理学中所谓的扩展相干态的生成函数。这一信息在最后一节中提供。
英文摘要：
We introduce a natural partial order in structurally natural finite subsets of the cobweb prefabs sets recently constructed by the present author. Whitney numbers of the second kind of the corresponding subposet which constitute Stirling like numbers triangular array are then calculated and the explicit formula for them is provided. Next, in the second construction we endow the set sums of prefabiants with such an another partial order that their Bell like numbers include Fibonacci triad sequences introduced recently by the present author in order to extend famous relation between binomial Newton coefficients and Fibonacci numbers onto the infinity of their relatives among whom there are also the Fibonacci triad sequences and binomial like coefficients (incidence coefficients included). The first partial order is F sequence independent while the second partial order is F sequence dependent where F is the so called admissible sequence determining cobweb poset by construction. An F determined cobweb posets Hasse diagram becomes Fibonacci tree sheathed with specific cobweb if the sequence F is chosen to be just the Fibonacci sequence. From the stand-point of linear algebra of formal series these are generating functions which stay for the so called extended coherent states of quantum physics. This information is delivered in the last section.
