关于$B$和$D$型第二类Stirling数的恒等式

Some identities involving second kind Stirling numbers of types $B$ and $D$

Eli Bagno, Riccardo Biagioli, David Garber

摘要:

利用Reiner定义的第二类Stirling数的类型$B$和$D$,推广了两个关于经典第二类Stirling数的著名恒等式.第一个恒等式将它们与欧拉数联系起来,第二个恒等式将它们解释为多项式环$R[x]$的两个标准基的元素之间的转移阵中的条目。最后,我们将这些恒等式推广到着色置换群$G_{m,n}$。

英文摘要:

Using Reiner's definition of Stirling numbers of the second kind in types $B$ and $D$, we generalize two well-known identities concerning the classical Stirling numbers of the second kind. The first identity relates them with Eulerian numbers and the second identity interprets them as entries in a transition matrix between the elements of two standard bases of the polynomial ring $R[x]$. Finally, we generalize these identities to the group of colored permutations $G_{m,n}$.
