This paper deals with the summation problem of power series of the form S b a (f ; x) = a≤k≤b f (k)x k , where 0 ≤ a < b ≤ ∞, and {f (k)} is a given sequence of numbers with k ∈ [a, b) or f (t) is a differentiable function defined on [a, b). We present a symbolic summation operator with its various expansions, and construct several summation formulas with… (More)

We define the Sheffer group of all Sheffer-type polynomials and prove the isomorphism between the Sheffer group and the Rior-dan group. An equivalence of the Riordan array pair and generalized Stirling number pair is also presented. Finally, we discuss a higher dimensional extension of Riordan array pairs. of the paper was generated while preparing for a… (More)

We have found that there are more than a dozen classical generating functions that could be suitably symbolized to yield various symbolic sum formulas by employing Mullin-Rota's theory of binomial enumeration. Various special formulas and identities involving well-known number sequences or polynomial sequences are presented as illustrative examples. The… (More)

This paper deals with the convergence of the summation of power series of the form S b a (f ; x) = a≤k≤b f (k)x k , where 0 ≤ a < b ≤ ∞, and {f (k)} is a given sequence of numbers with k ∈ [a, b) or f (t) a differentiable function defined on [a, b). Here the summation is found by using the symbolic operator approach shown in [4]. We will give a different… (More)

Here presented is the interrelationship between Eulerian polynomials, Eule-rian fractions and Euler-Frobenius polynomials, Euler-Frobenius fractions, B-splines, respectively. The properties of Eulerian polynomials and Eulerian fractions and their applications in B-spline interpolation and evaluation of Riemann zeta function values at odd integers are given.… (More)

Here we present a new method to construct the explicit formula of a sequence of numbers and polynomials generated by a linear recurrence relation of order 2. The applications of the method to the Fibonacci and Lucas numbers, Chebyshev polynomials, the generalized Gegenbauer-Humbert polynomials are also discussed. The derived idea provides a general method… (More)

Two types of symbolic summation formulas are reformulated using an extension of Mullin-Rota's substitution rule in [1], and several applications involving various special formulas and identities are presented as illustrative examples.
