A Note on Generalization of Combinatorial Identities Due to Gould and Touchard

open access: yesAxioms, 2023
Using a hypergeometric series approach, a general combinatorial identity is found in this note, and among its special cases are well-known and classical combinatorial identities due to Gould and Touchard.

A Family of Theta-Function Identities Based upon Combinatorial Partition Identities Related to Jacobi’s Triple-Product Identity

open access: yesMathematics, 2020
The authors establish a set of six new theta-function identities involving multivariable R-functions which are based upon a number of q-product identities and Jacobi’s celebrated triple-product identity.

Some combinatorial identities involving noncommuting variables [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
We derive combinatorial identities for variables satisfying specific sets of commutation relations. The identities thus obtained extend corresponding ones for $q$-commuting variables $x$ and $y$ satisfying $yx=qxy$.

Several identities containing central binomial coefficients and derived from series expansions of powers of the arcsine function

open access: yesResults in Nonlinear Analysis, 2021
In the paper, with the aid of the series expansions of the square or cubic of the arcsine function, the authors establish several possibly new combinatorial identities containing the ratio of two central binomial coefficients which are related to the ...

Some extensions for the several combinatorial identities

open access: yesAdvances in Difference Equations, 2021
In this paper, we give some extensions for Mortenson’s identities in series with the Bell polynomial using the partial fraction decomposition. As applications, we obtain some combinatorial identities involving the harmonic numbers.

On relationships between q-product identities and combinatorial partition identities [PDF]

open access: yesMathematica Moravica, 2020
Andrews et al. [2] discussed about the combinatorial partition identities. We aim to present some relationships between q-product identities and combinatorial partition identities, by using and combining known formulas.

New Expressions for Sums of Products of the Catalan Numbers

open access: yesAxioms, 2021
In this paper, we perform a further investigation for the Catalan numbers. By making use of the method of derivatives and some properties of the Bell polynomials, we establish two new expressions for sums of products of arbitrary number of the Catalan ...

Special Numbers and Polynomials Including Their Generating Functions in Umbral Analysis Methods

open access: yesAxioms, 2018
In this paper, by applying umbral calculus methods to generating functions for the combinatorial numbers and the Apostol type polynomials and numbers of order k, we derive some identities and relations including the combinatorial numbers, the Apostol ...
