简介:在这份报纸,我们将第一说明我们为什么应该介绍一它吗?打珍视集合的随机的微分方程并且我们为什么应该注意几乎到处问题。第二,我们将给不可分的Aumann类型Lebesgue的一个清楚的定义并且关于时间t珍视集合的随机的过程证明Lebesgue的measurability不可分。然后,我们将介绍一些新性质,特别证明珍视集合的Lebesgue积分的重要不平等。最后,我们将证明存在和的一个强壮的答案的唯一它吗?打珍视集合的随机的微分方程。关键词珍视集合的随机的过程-珍视集合的Lebesgue积分-珍视集合的随机的微分方程-强壮的解决方案先生(2000)题目分类60D05-60H10由中国(资助号码10771010)的国家自然科学基础支持了,PHR(IHLB),北京教育委员会,的研究资金中国;并且为科学研究19540140的Grant-in-Aid,日本
