human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "consistent probabilistic social choice"):
  Abstract: Two fundamental axioms in social choice theory are consistency with respect to a variable electorate and consistency with respect to components of similar alternatives. In the context of traditional non-probabilistic social choice, these axioms are incompatible with each other. We show that in the context of probabilistic social choice, these axioms uniquely characterize a function proposed by Fishburn (Rev. Econ. Stud., 51(4), 683--692, 1984). Fishburn's function returns so-called maximal lotteries, i.e., lotteries that correspond to optimal mixed strategies of the underlying plurality game. Maximal lotteries are guaranteed to exist due to von Neumann's Minimax Theorem, are almost always unique, and can be efficiently computed using linear programming.

Includes members:
  Member "welfare maximization entices participation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "rank maximal equal contribution a probabilistic social choice function")
  Member "set rationalizable choice and self stability":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "arrovian aggregation via pairwise utilitarianism")
