Maharam(1942)和Hoover-Keisler(1984)发展的具有饱和性质的非原子有限测度空间类,其特征在于取值于Banach空间的良控多值函数序列的Fatou(和Lebesgue)性质。随着多功能减少到功能,这Fatou特征也延伸到一个变种的封闭性发现在最优控制理论。结果是通过考虑概述的相关文献的确切和近似的Fatou引理措辞的Bochner整合。
The class of nonatomic finite measure spaces with the saturation property, as developed in Maharam (1942) and Hoover–Keisler (1984), is characterized by the Fatou (and Lebesgue) property of a well-dominated sequence of multifunctions taking values in a Banach space. With multifunctions reduced to functions, this Fatou characterization also extends to a variant of the closure property found in optimal control theory. The results are developed through a considered overview of the relevant literature on the exact and approximate Fatou lemma phrased in terms of Bochner integration.
