摘要
本文给出了两参数σ-域族的F4条件的一个等价命题,仅在F4条件下从同纹集出发讨论了两参数σ-域族的构造,证明了在F5条件下本文的同纹集就是局部可比较集,由此我们得到了伴随σ-域族和伴随鞅。
In this paper, a necessary and sufficient condition of F4 is given, a structure of a family of two-parameter fields is discussed only under condition F4 from similar veined sets, and it is proved that the similar veined sets are the comparable partially sets under condition F5. From this the accompanying family of two-parameter σ-fields and the accompanying martingale are got.
