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: "finitely generated ideal languages and synchronizing automata"
  Abstract: We study representations of ideal languages by means of strongly connected synchronizing automata. For every finitely generated ideal language L we construct such an automaton with at most 2^n states, where n is the maximal length of words in L. Our constructions are based on the De Bruijn graph.

Connected through hyperedge HE-1 (induced by source paper "representation of left ideal regular languages by synchronizing automata"):

    - "complexity of checking whether two automata are synchronized by the same language"
    - "reset complexity of ideal languages"
    - "testing for synchronization"
    - "principal ideal languages and synchronizing automata"

Connected through hyperedge HE-2 (induced by source paper "complexity of checking whether two automata are synchronized by the same language"):
