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 "characterizing solution concepts in terms of common knowledge of rationality"):
  Abstract: Characterizations of Nash equilibrium, correlated equilibrium, and rationalizability in terms of common knowledge of rationality are well known. Analogous characterizations of sequential equilibrium, (trembling hand) perfect equilibrium, and quasi-perfect equilibrium using results of Halpern [2009].

Includes members:
  Member "regret minimizing equilibria and mechanisms for games with strict type uncertainty":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "distance based equilibria in normal form games")
  Member "a logical characterization of iterated admissibility":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a conceptually well founded characterization of iterated admissibility using an all i know operator")
  Member "characterizing solution concepts in games using knowledge based programs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "from rules to runs a dynamic epistemic take on imperfect information games")
  Member "lexicographic probability conditional probability and nonstandard probability":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "a conceptually well founded characterization of iterated admissibility using an all i know operator")
