A New Hardy–Hilbert’s Integral Inequality with Two Internal Variables Involving Two Extended Derivative Functions of Higher-Order
摘要
By means of the weight functions, the idea of introduced parameters and the techniques of real analysis, a new Hardy–Hilbert’s integral inequality with two internal variables involving two extended derivative functions of higher-order is obtained. The equivalent statements of the best possible constant factor related to the parameters are considered. Some particular inequalities and the case of the reverses are provided.
