关于Almost-Riordan阵列群

On the Group of Almost-Riordan Arrays

Paul Barry

摘要:

本文研究Riordan数组群的一个超群,其中该群的元素由幂级数的三元组给出。我们表明,某些子集是子群,我们确定了一个正规子群的陪集对应于Riordan阵列。我们给出了一个例子的几乎Riordan阵列,已被研究的背景下,汉克尔和汉克尔加Toepliz矩阵,我们表明,适当选择的几乎Riordan阵列可以导致具有有趣的汉克尔变换性质的变换。

英文摘要:

We study a super group of the group of Riordan arrays, where the elements of the group are given by a triple of power series. We show that certain subsets are subgroups, and we identify a normal subgroup whose cosets correspond to Riordan arrays. We give an example of an almost-Riordan array that has been studied in the context of Hankel and Hankel plus Toepliz matrices, and we show that suitably chosen almost-Riordan arrays can lead to transformations that have interesting Hankel transform properties.
