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 "matrix approach to synchronizing automata"):
  Abstract: A word $w$ of letters on edges of underlying graph $\Gamma$ of deterministic finite automaton (DFA) is called synchronizing if $w$ sends all states of the automaton to a unique state. #R##N#J. Cerny discovered in 1964 a sequence of $n$-state complete DFA possessing a minimal synchronizing word of length $(n-1)^2$. The hypothesis, well known today as Cerny conjecture, claims that $(n-1)^2$ is a precise upper bound on the length of such a word for every complete $n$-state DFA. The hypothesis was formulated patently by Starke in 1966. #R##N#Some matrix approach to the problem is supposed and we consider a special class of matrices of mapping induced by words in the alphabet of letters on edges of the underlying graph.
