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 "about the domino problem in the hyperbolic plane from an algorithmic point of view"):
  Abstract: This paper is a contribution to the general tiling problem for the hyperbolic plane. It is an intermediary result between the result obtained by R. Robinson [ Invent. Math.   44  (1978) 259–264] and the conjecture that the problem is undecidable.

Includes members:
  Member "the domino problem of the hyperbolic plane is undecidable":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "row constrained effective sets of colourings in the 2 fold horocyclic tessellations of mathbb h 2 are sofic")
  Member "the domino problem of the hyperbolic plane is undecidable":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "row constrained effective sets of colourings in the 2 fold horocyclic tessellations of mathbb h 2 are sofic")
  Member "about the domino problem in the hyperbolic plane a new solution":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "noncooperative algorithms in self assembly")
