A reciprocal sum related to the Riemann ζ-function

open access: yes, 2017
This paper, we using the elementary method and several new inequalities to study the computational problem of one kind reciprocal sums related to the Riemann zeta-function at the point s = 4 , and give an explicit computational formula for it ...

Representations by degenerate Daehee polynomials

open access: yesOpen Mathematics, 2022
In this paper, we consider the problem of representing any polynomial in terms of the degenerate Daehee polynomials and more generally of the higher-order degenerate Daehee polynomials.

Determinants of the RSFPLR Circulant Matrices with the Jacobsthal Numbers

open access: yes, 2020
In this paper, we study a special type of circulant matrices involving the Jacobsthal and Jacobsthal-Lucas numbers. We mainly calculate the determinant of these matrices using inverse factorization of polynomials. 2010 Mathematics Subject Classification:

Some recurrence formulas for the Hermite polynomials and their squares

open access: yesOpen Mathematics, 2018
In this paper, by making use of the generating function methods and Padé approximation techniques, we establish some new recurrence formulas for the Hermite polynomials and their squares.

Some identities related to degenerate Stirling numbers of the second kind

open access: yesDemonstratio Mathematica, 2022
The degenerate Stirling numbers of the second kind were introduced as a degenerate version of the ordinary Stirling numbers of the second kind. They appear very frequently when one studies various degenerate versions of some special numbers and ...

Formal inverses of the generalized Thue-Morse sequences and variations of the Rudin-Shapiro sequence [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
A formal inverse of a given automatic sequence (the sequence of coefficients of the composition inverse of its associated formal power series) is also automatic.

Barker sequences of odd length [PDF]

open access: yes, 2015
A Barker sequence is a binary sequence for which all nontrivial aperiodic autocorrelations are at most 1 in magnitude. An old conjecture due to Turyn asserts that there is no Barker sequence of length greater than 13.

Fully degenerate Bell polynomials associated with degenerate Poisson random variables

open access: yesOpen Mathematics, 2021
Many mathematicians have studied degenerate versions of quite a few special polynomials and numbers since Carlitz’s work (Utilitas Math. 15 (1979), 51–88). Recently, Kim et al.
