摘要
有很多实际问题可以转化为关于[a,b]上的函数f(x)的平均值函数的极值问题的研究.本文给出了一个便于极值分析的函数空间,证明了当f(x)时亦有,拓宽了[1]中的相应结论的应用范围.进一步,我们还考虑了这一结果在二维情形下的推广.
et f(x) define in [a,b], F(x) denote its mean value function,i. e.Many practical problems can be transformed into the discussions of the extremal value of F(x). In this paper,we constructed a function space in which the discussions of the extremal problem are quiet convenient, and proved that implies F(x). This improved the results of [fi. Furthermore,we extended this result to the case of two-dimensions.
