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 "mechanical proofs of properties of the tribonacci word"):
  Abstract: We implement a decision procedure for answering questions about a class of infinite words that might be called (for lack of a better name) "Tribonacci-automatic". This class includes, for example, the famous Tribonacci word T = 0102010010202 ..., the fixed point of the morphism 0 -> 01, 1 -> 02, 2 -> 0. We use it to reprove some old results about the Tribonacci word from the literature, such as assertions about the occurrences in T of squares, cubes, palindromes, and so forth. We also obtain some new results.

Includes members:
  Member "decision algorithms for fibonacci automatic words with applications to pattern avoidance":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "abelian square rich words")
  Member "on the number of unbordered factors":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "abelian square rich words")
  Member "primitive words and lyndon words in automatic and linearly recurrent sequences":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "sums of palindromes an approach via automata")
  Member "subword complexity and k synchronization":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "closed palindromic rich privileged trapezoidal and balanced words in automatic sequences")
  Member "enumeration and decidable properties of automatic sequences":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "minimal automaton for multiplying and translating the thue morse set")
  Member "periodicity repetitions and orbits of an automatic sequence":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "minimal automaton for multiplying and translating the thue morse set")
