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 "complexity of checking whether two automata are synchronized by the same language"):
  Abstract: A deterministic finite automaton is said to be synchronizing if it has a reset word, i.e. a word that brings all states of the automaton to a particular one. We prove that it is a PSPACE-complete problem to check whether the language of reset words for a given automaton coincides with the language of reset words for some particular automaton.

Includes members:
  Member "reset complexity of ideal languages":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a characterization of completely reachable automata")
  Member "finitely generated ideal languages and synchronizing automata":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "representation of left ideal regular languages by synchronizing automata")
  Member "slowly synchronizing automata and digraphs":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "cerny starke conjecture from the sixties of xx century")
