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 "on the toggling branching recurrence of computability logic"):
  Abstract: We introduce a new, substantially simplified version of the toggling-branching recurrence operation of Computability Logic, prove its equivalence to Japaridze's old, "canonical" version, and also prove that both versions preserve the static property of their arguments.

Includes members:
  Member "the taming of recurrences in computability logic through cirquent calculus part ii":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "fundamentals of computability logic")
  Member "a new face of the branching recurrence of computability logic":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fundamentals of computability logic")
  Member "the countable versus uncountable branching recurrences in computability logic":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "fundamentals of computability logic")
  Member "toggling operators in computability logic":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "fundamentals of computability logic")
