摘要翻译：
对于所有联盟策略证明的社会选择函数，我们给出了一个结构定理，它的值域是一个给定的较大方案集的基数的子集。我们在允许投票人/代理人表示无关紧要，并且域由任意基数社会的偏好分布组成的情况下提供了这一点。该定理以表示公式的形式出现，可以用来构造所考虑的所有函数。

英文摘要：
  We give a structure theorem for all coalitionally strategy-proof social choice functions whose range is a subset of cardinality two of a given larger set of alternatives.   We provide this in the case where the voters/agents are allowed to express indifference and the domain consists of profiles of preferences over a society of arbitrary cardinality. The theorem, that takes the form of a representation formula, can be used to construct all functions under consideration.
