摘要
应用欧氏空间理论把Cauchy不等式推广到可数无穷情形,作为其应用给出了正项级数收敛的一个判别定理,并给出了和的上界估计.
Cauchy inequality is extended to countable infinite circumstances by using the theories of Euclidean space. As its application ,a theorem of differentiating positive convergent series is established and an estimate of upper boundary of sum is given.
