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 4 map graphs and 1 planar graphs and their recognition problem"):
  Abstract: We establish a one-to-one correspondence between 1-planar graphs and general and hole-free 4-map graphs and show that 1-planar graphs can be recognized in polynomial time if they are crossing-augmented, fully triangulated, and maximal 1-planar, respectively, with a polynomial of degree 120, 3, and 5, respectively.

Includes members:
  Member "parameterized complexity of 1 planarity":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "an experimental study of a 1 planarity testing and embedding algorithm")
  Member "recognizing optimal 1 planar graphs in linear time":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fan crossing free graphs")
  Member "on the recognition of fan planar and maximal outer fan planar graphs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "fan crossing free graphs")
  Member "1 visibility representations of 1 planar graphs":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "fan crossing free graphs")
