  Abstract:

In this paper, it is shown that an extended Hardy-Hilbert's integral inequality with weights can be established by introducing a power-exponent function of the form $ ax^{1 + x}(a> 0,x in [0, + infty ))$, and the coefficient $ frac{pi }{left( a right)^{1/q} left( b right)^{1/p}sin pi/p}$ is shown to be the best possible constant in the inequality. In particular, for the case $ p = 2$, some extensions on the classical Hilbert's integral inequality are obtained. As applications, generalizations of Hardy-Littlewood's integral inequality are given. ;
