absolutely discontinuous function

The fundamental purpose of this paper is to point out main features and several sufficient conditions of continuous function becoming absolute continuous function, introduce and apply an important theorem.

所述内容对深刻理解绝对连续函数类具有重要意义。

The authors discuss the problem whether the condition in the definition of a reproducing kernel space can be weakened or not and obtaine two conclusions as follows:(1) The conditions, u(x) being a real continuous function in interval [a,b] and u′(x)∈L~2[a,b], can not deduce the conclusion that u(x) is an absolute continuous function in interval [a,b].

讨论再生核空间W12 [a,b]定义中的条件是否可以减弱的问题,得到下面的两个结论:(1)条件u(x)是[a,b]上实的连续函数且u′(x)∈L2 [a,b]不能推出u(x)是[a,b]上实的绝对连续函数; (2)再生核空间W12 [a,b]定义中的条件改为u(x)在[a,b]是连续函数或连续囿变函数,那么函数空间不再是再生核空间。
