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 "the finite tiling problem is undecidable in the hyperbolic plane"):
  Abstract: In this paper, we consider the finite tiling problem which was proved undecidable in the Euclidean plane by Jarkko Kari, see [5]. Here, we prove that the same problem for the hyperbolic plane is also undecidable.

Includes members:
  Member "about the domino problem in the hyperbolic plane from an algorithmic point of view":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the injectivity of the global function of a cellular automaton in the hyperbolic plane is undecidable")
  Member "about the domino problem in the hyperbolic plane a new solution":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "noncooperative algorithms in self assembly")
  Member "on a characterization of cellular automata in tilings of the hyperbolic plane":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a family of weakly universal cellular automata in the hyperbolic plane with two states")

The 40 classes are: cs.NA(Numerical Analysis), cs.MM(Multimedia), cs.LO(Logic in Computer Science), cs.CY(Computers and Society), cs.CR(Cryptography and Security), cs.DC(Distributed, Parallel, and Cluster Computing), cs.HC(Human-Computer Interaction), cs.CE(Computational Engineering, Finance, and Science), cs.NI(Networking and Internet Architecture), cs.CC(Computational Complexity), cs.AI(Artificial Intelligence), cs.MA(Multiagent Systems), cs.GL(General Literature), cs.NE(Neural and Evolutionary Computing), cs.SC(Symbolic Computation), cs.AR(Hardware Architecture), cs.CV(Computer Vision and Pattern Recognition), cs.GR(Graphics), cs.ET(Emerging Technologies), cs.SY(Systems and Control), cs.CG(Computational Geometry), cs.OH(Other Computer Science), cs.PL(Programming Languages), cs.SE(Software Engineering), cs.LG(Machine Learning), cs.SD(Sound), cs.SI(Social and Information Networks), cs.RO(Robotics), cs.IT(Information Theory), cs.PF(Performance), cs.CL(Computation and Language), cs.IR(Information Retrieval), cs.MS(Mathematical Software), cs.FL(Formal Languages and Automata Theory), cs.DS(Data Structures and Algorithms), cs.OS(Operating Systems), cs.GT(Computer Science and Game Theory), cs.DB(Databases), cs.DL(Digital Libraries), cs.DM(Discrete Mathematics). Directly output the class name.
