第1节。导论.设两个概率空间(X,μ,v)和(Y,μ,v)。对于X × Y的一个子集D和一个真实的数d ≥ 0,我们考虑下面的问题(MP)是否存在X × Y上的一个测度»,它以μ和ν作为边缘,并且使得λ(D)≥ 1 − d?这个问题来自于斯特拉森的论文[12],其中讨论了波兰空间上的Borel概率。此外,许多作者在更一般的环境中进行了研究(参见。[2],[4]-[7],[11]-[13])。
§1. Introduction . Let two probability spaces ( X , , μ,) and ( Y , ℬ, ν) be given. For a subset D of X × Y and a real number d ≥ 0 we consider the following problem (MP) Does there exist a measure » on X × Y having μ and ν as marginals and such that λ ( D ) ≥ 1 − d ? This problem comes from Strassen's paper [12], where Borel probabilities on Polish spaces were treated. Further, it was investigated by many authors in more general settings (cf. [2], [4]-[7], [11]-[13]).
