An extended reverse Hardy–Hilbert’s inequality in the whole plane [PDF]

open access: yesJournal of Inequalities and Applications, 2018
Using weight coefficients, a complex integral formula, and Hermite–Hadamard’s inequality, we give an extended reverse Hardy–Hilbert’s inequality in the whole plane with multiparameters and a best possible constant factor.

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 ...

On New Extensions of Hilbert's Integral Inequality

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
It is shown that some new extensions of Hilbert's integral inequality with parameter λ(λ>1/2) can be established by introducing a proper weight function. In particular, when λ=1, a refinement of Hilbert's integral inequality is obtained. As applications,

A Generalization on Some New Types of Hardy-Hilbert’s Integral Inequalities

open access: yesJournal of Function Spaces and Applications, 2013
Sulaiman presented, in 2008, new kinds of Hardy-Hilbert’s integral inequality in which the weight function is homogeneous. In this paper, we present a generalization on the kinds of Hardy-Hilbert’s integral inequality.

On Some Extensions of Hardy-Hilbert's Inequality and Applications

open access: yesJournal of Inequalities and Applications, 2008
By introducing some parameters we establish an extension of Hardy-Hilbert's integral inequality and the corresponding inequality for series. As an application, the reverses, some particular results and their equivalent forms are considered.
