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 "dependent types for extensive games"):
  Abstract: Extensive games are tools largely used in economics to describe decision processes ofa community of agents. In this paper we propose a formal presentation based on theproof assistant COQ which focuses mostly on infinite extensive games and theircharacteristics. COQ proposes a feature called "dependent types", which meansthat the type of an object may depend on the type of its components. For instance,the set of choices or the set of utilities of an agent may depend on the agentherself. Using dependent types, we describe formally a very general class of gamesand strategy profiles, which corresponds somewhat to what game theorists are used to.We also discuss the notions of infiniteness in game theory and how this can beprecisely described.

Includes members:
  Member "a simple case of rationality of escalation":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "intelligent escalation and the principle of relativity")
  Member "common knowledge logic in a higher order proof assistant":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "tool support for reasoning in display calculi")
