摘要:利用改进了的Cauchy不等式对1个类似于Hardy-Hilbert不等式的不等式作了改进.建立了1个新的不等式:〖DD(〗∞〖〗n=1〖DD)〗〖DD(〗∞〖〗m=1〖DD)〗〖SX(〗ambn〖〗ln m+ln n+1〖SX)〗<π〖JB({〗〖DD(〗∞〖〗n=1〖DD)〗na2n〖DD(〗∞〖〗n=1〖DD)〗nb2n〖JB)}〗1/2(1-R)1/2.其中R=〖JB((〗〖SX(〗(α,γ)〖〗‖α‖〖SX)〗-〖SX(〗(β,γ)〖〗‖β‖〖SX)〗〖JB))〗2.

关键词: Hardy-Hilbert不等式, Cauchy不等式, 权系数

Abstract: In this paper,by means of the refined Cauchy’s inequality,a inequality similar to Hilbert’s inequality is improved.A new inequality is built:〖DD(〗∞〖〗n=1〖DD)〗〖DD(〗∞〖〗m=1〖DD)〗(ambn/(ln m+ln n+1)<π〖JB({〗〖DD(〗∞〖〗n=1〖DD)〗na2n〖DD(〗∞〖〗n=1〖DD)〗nb2n〖JB)}〗1/2(1-R)1/2.where R=〖JB((〗((α,γ)/‖α‖)-(β,γ)/‖β‖〖JB))〗2.

Key words: Hardy-Hilbert's inequality, Cauchy&rsquo, s inequality, weight coefficient
