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 "walrasian dynamics in multi unit markets"):
  Abstract: In a multi-unit market, a seller brings multiple units of a good and tries to sell them to a set of buyers equipped with monetary endowments. While a Walrasian equilibrium does not always exist in this model, natural relaxations of the concept that retain its desirable fairness properties do exist. #R##N#We study the dynamics of (Walrasian) envy-free pricing algorithms in this environment, showing that for any such pricing algorithm, the best response dynamic process converges to a pure Nash equilibrium with small loss in revenue and welfare. Moreover, we generalize these bounds to capture all the Nash equilibria for a large class of (monotone) pricing algorithms.
