human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "on the topological complexity of infinitary rational relations"
  Abstract: We prove in this paper that there exists some infinitary rational relations which are analytic but non Borel sets, giving an answer to a question of Simonnet [Automates et Th\'eorie Descriptive, Ph. D. Thesis, Universit\'e Paris 7, March 1992].

Connected through hyperedge HE-1 (induced by source paper "highly undecidable problems for infinite computations"):
  with members:
    - "borel hierarchy and omega context free languages"
    - "on recognizable languages of infinite pictures"
    - "highly undecidable problems about recognizability by tiling systems"
    - "undecidable problems about timed automata"
    - "borel ranks and wadge degrees of context free omega languages"

Connected through hyperedge HE-2 (induced by source paper "wadge degrees of infinitary rational relations"):
  with members:
    - "on infinitary rational relations and borel sets"
    - "an effective extension of the wagner hierarchy to blind counter automata"
    - "borel ranks and wadge degrees of context free omega languages"

Connected through hyperedge HE-3 (induced by source paper "on the continuity set of an omega rational function"):
  with members:
    - "on infinitary rational relations and borel sets"
    - "borel ranks and wadge degrees of context free omega languages"

Connected through hyperedge HE-4 (induced by source paper "on infinite real trace rational languages of maximum topological complexity"):

    - "on recognizable languages of infinite pictures"
