Abstract

By applying the method of weight functions and the technique of real analysis, a multidimensional Hilbert-type integral inequality with multi-parameters and the best possible constant factor related to the gamma function is given. The equivalent forms and the reverses are obtained. We also consider the operator expressions and a few particular results related to the kernels of non-homogeneous and homogeneous.

Summary

Suppose that p

We have the following well-known Hardy-Hilbert integral inequality (cf [ ]):. Where the constant factor π sin(π /p) is best possible. > , b q > , we still have the discrete variant of the above inequality with the same best constant π sin(π /p) as follows: ambn < π m + n sin(π/p). Inequalities ( ) and ( ) are important in the analysis and its applications (cf [ – ]). In , by introducing an independent parameter λ ∈
