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 "central approximation in statistical physics and information theory"):
  Abstract: In statistical physics and information theory, although the exponent of the partition function is often of our primary interest, there are cases where one needs more detailed information. In this paper, we present a general framework to study more precise asymptotic behaviors of the partition function, using the central approximation in conjunction with the method of types.

Includes members:
  Member "counting in graph covers a combinatorial characterization of the bethe entropy function":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "pseudocodeword based decoding of quantum stabilizer codes")
  Member "connection between annealed free energy and belief propagation on random factor graph ensembles":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "threshold saturation for spatially coupled ldpc and ldgm codes on bms channels")
