用无限多个线性约束来表示低预见性的标准相干准则。对于本质上定义在有限可能性空间上的有限赌博集上的较低预见,我们给出了只使用有限个约束条件的该判据的重新表述。任何这种较低的预见性是相干的,如果它位于由这些约束所定义的凸多面体内。这个多面体的顶点是给定赌博集的极端相干下预见。我们的重新表述使计算它们成为可能。我们展示了如何做到这一点,并说明了过程及其结果。

英文摘要:
The standard coherence criterion for lower previsions is expressed using an infinite number of linear constraints. For lower previsions that are essentially defined on some finite set of gambles on a finite possibility space, we present a reformulation of this criterion that only uses a finite number of constraints. Any such lower prevision is coherent if it lies within the convex polytope defined by these constraints. The vertices of this polytope are the extreme coherent lower previsions for the given set of gambles. Our reformulation makes it possible to compute them. We show how this is done and illustrate the procedure and its results.
