摘要翻译：
一组理想的赌博构成了一种具有有趣的几何解释的相当一般类型的不确定性模型。我们对这类模型及其合理性判据作了一般性讨论。我们研究了它们的可交换性评价，并证明了de Finetti的有限和无限表示定理的对应关系。我们证明了用计数向量表示的有限表示具有很好的几何解释，用频率向量表示的有限表示与多元Bernstein（基）多项式有关。我们还揭示了更新的可交换模型的表示之间的关系，讨论了可交换性下的保守推理（自然扩张）和可交换序列的扩张。

英文摘要：
Sets of desirable gambles constitute a quite general type of uncertainty model with an interesting geometrical interpretation. We give a general discussion of such models and their rationality criteria. We study exchangeability assessments for them, and prove counterparts of de Finetti's finite and infinite representation theorems. We show that the finite representation in terms of count vectors has a very nice geometrical interpretation, and that the representation in terms of frequency vectors is tied up with multivariate Bernstein (basis) polynomials. We also lay bare the relationships between the representations of updated exchangeable models, and discuss conservative inference (natural extension) under exchangeability and the extension of exchangeable sequences.
