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 "computation with narrow ctcs"):
  Abstract: We examine some variants of computation with closed timelike curves (CTCs), where various restrictions are imposed on the memory of the computer, and the information carrying capacity and range of the CTC. We give full characterizations of the classes of languages recognized by polynomial time probabilistic and quantum computers that can send a single classical bit to their own past. Such narrow CTCs are demonstrated to add the power of limited nondeterminism to deterministic computers, and lead to exponential speedup in constant-space probabilistic and quantum computation.

Includes members:
  Member "probabilistic and quantum finite automata with postselection":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "postselecting probabilistic finite state recognizers and verifiers")
  Member "unbounded error quantum computation with small space bounds":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "quantum finite automata survey status and research directions")
  Member "succinctness of two way probabilistic and quantum finite automata":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "quantum finite automata survey status and research directions")
  Member "two way finite automata with quantum and classical states":
    also connected through other hyperedges:
