The main objective of this paper is to prove Hilbert-type and Hardy-Hilbert-type inequalities with a product-type homogeneous kernel, thus generalizing a result obtained in [Z. Xie, Z.

By the use of Hermite–Hadamard’s inequality and weight functions, a half-discrete Hilbert-type inequality in the whole plane with the kernel of hyperbolic cotangent function and multi-parameters is given.

The equivalent forms, two kinds of particular inequalities, the operator expressions and some equivalent reverses are considered.     

A Unified Treatment of Half-Discrete Hilbert-Type Inequalities with a Homogeneous Kernel

In this paper we provide a unified treatment of half-discrete Hilbert-type inequalities with a general homogeneous kernel. The main results are proved for the case of non-conjugate exponents. A special emphasis is given to determining conditions under which these inequalities include the best possible constants. As an application, we consider some operator expressions closely connected to established inequalities. Finally, we also provide improvements of derived half-discrete inequalities by virtue of the Hermite-Hadamard inequality.

Discrete Hilbert-type inequalities with general homogeneous kernels

The main objective of this paper is an unified treatment of discrete Hilbert-type inequalities with homogeneous kernels.

The obtained results are then applied to various settings considering homogeneous functions of a negative real degree. In such a way, we obtain the generalizations of numerous results, previously known from the literature.
