向量值函数连续与可导的关系

通过构造反例的方法,充分论证取值于X的向量值函数强连续只是弱可导的必要条件,而且还存在着强绝对连续并不几乎处处有弱导数的向量值函数.

Some properties of monotone set functions defined by Choquet integral

In this paper, some properties of the monotone set function defined by theChoquet integral are discussed. It is shown that several important structural characteristics of theoriginal set function, such as weak null-additivity, strong order continuity, property (s) andpseudomelric generating property, etc., are preserved by the new set function. It is also shown thatC-integrability assumption is inevitable for the preservations of strong order continuous andpseudometric generating property.
