摘要: 运用权函数、参量化和实分析方法, 建立一个新的Hardy-Hilbert型积分不等式,该积分不等式涉及齐次核1/(x+y)λ+2n (λ >0)和n阶导函数;进一步证明了该积分不等式涉及多个参量和最佳常数因子的等价陈述,给出了若干取特殊参数值(λ1=λ/r, λ2=λ/s (r>1, 1/r+1/s=1);λ=1, r=q, s=p)的不等式。Abstract: By means of the weight functions, the idea of introducing parameters and the method of real analysis, a new Hardy-Hilbert-type integral inequality with the homogeneous kernel as 1/(x+y)λ+2n (λ >0) involving the derivative functions of n-order is established. The equivalent statements of the best possible constant factor related to several parameters are proved, and some particular (λ1=λ/r, λ2=λ/s (r>1, 1/r+1/s=1);λ=1, r=q, s=p) inequalities are gived.
