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 "asymptotics of entropy rate in special families of hidden markov chains"):
  Abstract: We derive an asymptotic formula for entropy rate of a hidden Markov chain around a "weak Black Hole". We also discuss applications of the asymptotic formula to the asymptotic behaviors of certain channels.

Includes members:
  Member "derivatives of entropy rate in special families of hidden markov chains":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "analyticity of entropy rates of continuous state hidden markov models")
  Member "the entropy of a binary hidden markov process":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a randomized approach to the capacity of finite state channels")
  Member "from finite system entropy to entropy rate for a hidden markov process":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "on analytic properties of entropy rate")
