面向阶级分离社会的集体战略凝聚
Collective strategy condensation towards class-separated societies
摘要：
在物理学中，玻色粒子的波函数在系统经历玻色-爱因斯坦凝聚时坍缩。在博弈论中，代理人的策略描述了参与某个行动过程的概率。在竞争的情况下，也就是说，当与别人做同样的事情会受到惩罚时，策略会有所不同。我们研究了当代理人不仅对他们的绝对表现感兴趣时会发生什么，而且还相对于其他人。这种偏好，表示嫉妒，是诱导不同的社会阶层的出现，通过集体战略凝聚过渡。下层阶级的成员追求相同的策略，类似于玻色-爱因斯坦凝聚，上层阶级保持个人主义。
英文摘要：
In physics, the wavefunctions of bosonic particles collapse when the system undergoes a Bose-Einstein condensation. In game theory, the strategy of an agent describes the probability to engage in a certain course of action. Strategies are expected to differ in competitive situations, namely when there is a penalty to do the same as somebody else. We study what happens when agents are interested how they fare not only in absolute terms, but also relative to others. This preference, denoted envy, is shown to induce the emergence of distinct social classes via a collective strategy condensation transition. Members of the lower class pursue identical strategies, in analogy to the Bose-Einstein condensation, with the upper class remaining individualistic.
