Finite multi-utility representable preferences and Pareto orderings
研究了哪些偏序集可以表示为有限多个效用函数的交集，并将该结果与Dushnik和Miller提出的偏序集序维概念联系起来。
A characterization of the posets that admit a finite multi-utility representation is presented. This result is also connected to the concept of order dimension of a poset as defined by Dushnik and Miller (1941).
