Sums of finite products of Chebyshev polynomials of the second kind and of Fibonacci polynomials [PDF]

open access: yesJournal of Inequalities and Applications, 2018
In this paper, we consider sums of finite products of Chebyshev polynomials of the second kind and of Fibonacci polynomials and derive Fourier series expansions of functions associated with them. From these Fourier series expansions, we can express those

Studies in Sums of Finite Products of the Second, Third, and Fourth Kind Chebyshev Polynomials

open access: yesMathematics, 2020
In this paper, we consider three sums of finite products of Chebyshev polynomials of two different kinds, namely sums of finite products of the second and third kind Chebyshev polynomials, those of the second and fourth kind Chebyshev polynomials, and ...

Extended Wang sum and associated products.

open access: yesPLoS ONE, 2022
The Wang sum involving the exponential sums of Lerch's Zeta functions is extended to the finite sum of the Huwitz-Lerch Zeta function to derive sums and products involving cosine and tangent trigonometric functions.

The Equivalence of the Charge Interaction Sum and the Ionic Strength

open access: yesChemical Thermodynamics and Thermal Analysis, 2022
The electrostatic interaction among a neutral and finite set of point charges is based on the sum of their pairwise charge products, zizj, yet many analyses yield terms which simply contain a sum of the squares of the separate charges, corresponding to ...

Infinite Series and Logarithmic Integrals Associated to Differentiation with Respect to Parameters of the Whittaker Mκ,μ(x) Function I

open access: yesAxioms, 2023
In this paper, first derivatives of the Whittaker function Mκ,μx are calculated with respect to the parameters. Using the confluent hypergeometric function, these derivarives can be expressed as infinite sums of quotients of the digamma and gamma ...

Sums of finite products of Genocchi functions

open access: yesAdvances in Difference Equations, 2017
In a previous work, it was shown that Faber-Pandharipande-Zagier and Miki’s identities can be derived from a polynomial identity which in turn follows from a Fourier series expansion of sums of products of Bernoulli functions.

Sums of finite products of Bernoulli functions

open access: yesAdvances in Difference Equations, 2017
In this paper, we consider three types of functions given by sums of finite products of Bernoulli functions and derive their Fourier series expansions. In addition, we express each of them in terms of Bernoulli functions.

Fourier Series for Functions Related to Chebyshev Polynomials of the First Kind and Lucas Polynomials

open access: yesMathematics, 2018
In this paper, we derive Fourier series expansions for functions related to sums of finite products of Chebyshev polynomials of the first kind and of Lucas polynomials. From the Fourier series expansions, we are able to express those two kinds of sums of
