式(1)稱為Hardy-Hilbert積分不等式, 它在分析學(xué)中有重要的應(yīng)用.

文獻(xiàn)[1]給出了如下一個(gè)新的較精確的半離散Hilbert不等式:

1 引理及證明

為了方便起見, 先介紹一些符號:

證明見文獻(xiàn)[2].

證明過程見文獻(xiàn)[2].

2 主要結(jié)果

為方便起見, 再引入一些符號:

證明 由引理1和引理2, 有:

即(5)式得證.

Hilbert-type inequality are important in analysis and its applications. In this paper, a half-discrete Hilbert-type inequality is investigated. By using the way of weight functions and the techniuque of real analysis and a sharpening of H?lder’s inequality, some improvements of Hardy-Hilbert’s inequality are given, a few new inequalities are established.
