A characterization of proportionally representative committees
刻画了满足“固体联盟比例性”公理的委员会，将其描述为一类最小需求规则的结果范围，这对研究选举制度和比例代表制的学者有参考价值。
A well-known axiom for proportional representation is Proportionality for Solid Coalitions (PSC). We characterize committees satisfying PSC as the range of outcomes obtained by the class of Minimal Demand rules, which generalizes an approach pioneered by eminent philosopher Sir Michael Dummett.
