A Study on Some New Reverse Hilbert-Type Inequalities and Its Generalizations on Time Scales

open access: yesJournal of Mathematics, 2022
This study develops the study of reverse Hilbert-type inequalities on time scales where we can establish some new generalizations of reverse Hilbert-type inequalities via supermultiplicative functions on time scales by applying reverse Hölder ...

Reverse Hilbert's type integral inequalities [PDF]

open access: yesMathematical Inequalities & Applications, 2014
In this paper, we are motivated by some newer Hilbert-Pachpatte inequalities, and that we derive some similar (but reverse) inequalities. Mathematics subject classification (2010): 26D15.

Non injectivity of the q-deformed von Neumann algebra [PDF]

open access: yes, 2004
We prove that the von Neumann algebra generated by q-gaussians is not injective as soon as the dimension of the underlying Hilbert space is greater than 1. Our approach is based on a vector valued Khintchine type inequality for Wick products.

A Hilbert type inequality

open access: yesTamkang Journal of Mathematics, 2000
In this paper we obtain a new inequality of Hilbert type for a finite number of nonnegative sequences of real numbers from which we can recover as a special case an inequality due to Pachpatte. We also obtain an integral variant of the inequality.

Some Local Fractional Hilbert-Type Inequalities

open access: yesFractal and Fractional, 2023
The main purpose of this paper is to prove some new local fractional Hilbert-type inequalities. Our general results are applicable to homogeneous kernels. Furthermore, the best possible constants in terms of local fractional hypergeometric function are obtained.

On inequalities of Hilbert's type [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2007
By introducing the function 1/(min{x, y}), we establish several new inequalities similar to Hilbert's type inequality. Moreover, some further unification of Hardy-Hilbert's and Hardy-Hilbert's type integral inequality and its equivalent form with the best constant factor are proved, which contain the classic Hilbert's inequality as special case.
