Constructing Exponential Riordan Arrays from Their A and Z Sequences
نویسنده
چکیده
One of the most fundamental results concerning Riordan arrays is that they have a sequence characterization [13, 18]. This normally involves two sequences, called the A-sequence and the Z-sequence. For exponential Riordan arrays [9] (see Appendix), this characterization is equivalent to the fact that the production matrix [11] of an exponential array [g, f ], with A-sequence A(t) and Z-sequence Z(t) has bivariate generating function

A Study of Integer Sequences, Riordan Arrays, Pascal-like Arrays and Hankel Transforms
We study integer sequences and transforms that operate on them. Many of these transforms are defined by triangular arrays of integers, with a particular focus on Riordan arrays and Pascal-like arrays. In order to explore the structure of these transforms, use is made of methods coming from the theory of continued fractions, hypergeometric functions, orthogonal polynomials and most importantly f...
متن کاملEulerian Polynomials as Moments, via Exponential Riordan Arrays
Using the theory of exponential Riordan arrays and orthogonal polynomials, we demonstrate that the Eulerian polynomials and the shifted Eulerian polynomials are moment sequences for a simple family of orthogonal polynomials. The coefficient arrays of these families of orthogonal polynomials are shown to be exponential Riordan arrays. Using the theory of orthogonal polynomials we are then able t...
متن کاملA Note on Krawtchouk Polynomials and Riordan Arrays
The Krawtchouk polynomials play an important role in various areas of mathematics. Notable applications occur in coding theory [11], association schemes [4], and in the theory of group representations [21, 22]. In this note, we explore links between the Krawtchouk polynomials and Riordan arrays, of both ordinary and exponential type, and we study integer sequences defined by evaluating the Kraw...
متن کاملA/Z characterization of Riordan arrays
In the realm of the Riordan group, we consider the characterization of Riordan arrays by means of the Aand Z-sequences. It corresponds to a horizontal construction of a Riordan array, whereas the traditional approach is through column generating functions. We show how the Aand Z-sequences of the product of two Riordan arrays are derived from those of the two factors; similar results are obtaine...
متن کاملSome Observations on the Lah and Laguerre Transforms of Integer Sequences
We study the Lah and related Laguerre transforms within the context of exponential Riordan arrays. Links to the Stirling numbers are explored. Results for finite matrices are generalized, leading to a number of useful matrix factorizations. In this note, we shall consider integer sequences a : N 0 → Z with general term a n = a(n). Normally, sequences will be described by either by their ordinar...
