A Reverse Hardy–Hilbert’s Inequality Containing Multiple Parameters and One Partial Sum

open access: yesMathematics, 2022
In this work, by introducing multiple parameters and utilizing the Euler–Maclaurin summation formula and Abel’s partial summation formula, we first establish a reverse Hardy–Hilbert’s inequality containing one partial sum as the terms of double series ...

Relationship between alternating sums of powers of integers and sums of powers of integers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this note, we consider the alternating sums of powers of integers. We write alternating sum of powers of integers as the linear combination of sums of powers of integers. As the coefficients, the special value of the Euler polynomial appears.

Euler-type sums involving multiple harmonic sums and binomial coefficients

open access: yesOpen Mathematics, 2021
In this paper, we mainly show that generalized Euler-type sums of multiple harmonic sums with reciprocal binomial coefficients can be expressed in terms of rational linear combinations of products of classical multiple zeta values (MZVs) and multiple ...

Continuous Stability TS Fuzzy Systems Novel Frame Controlled by a Discrete Approach and Based on SOS Methodology

open access: yesMathematics, 2021
Generally, the continuous and discrete TS fuzzy systems’ control is studied independently. Unlike the discrete systems, stability results for the continuous systems suffer from conservatism because it is still quite difficult to apply non-quadratic ...

Approximations of the generalized-Euler-constant function and the generalized Somos’ quadratic recurrence constant

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we provide an estimate for approximating the generalized-Euler-constant function γ(z)=∑k=1∞zk−1(1k−lnk+1k) $\gamma (z)=\sum_{k=1}^{\infty }z ^{k-1} (\frac{1}{k}-\ln \frac{k+1}{k} )$ by its partial sum γN−1(z) $\gamma _{N-1}(z)$ when ...
