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 "a simple case of rationality of escalation"):
  Abstract: Escalation is the fact that in a game (for instance an auction), the agents play forever. It is not necessary to consider complex examples to establish its rationality. In particular, the $0,1$-game is an extremely simple infinite game in which escalation arises naturally and rationally. In some sense, it can be considered as the paradigm of escalation. Through an example of economic games, we show the benefit economics can take of coinduction.

Includes members:
  Member "coalgebraic analysis of subgame perfect equilibria in infinite games without discounting":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a compositional treatment of iterated open games")
  Member "rationality and escalation in infinite extensive games":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a compositional treatment of iterated open games")
  Member "feasibility desirability games for normal form games choice models and evolutionary games":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "intelligent escalation and the principle of relativity")
