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 "holographic transformation for quantum factor graphs"):
  Abstract: Recently, a general tool called a holographic transformation, which transforms an expression of the partition function to another form, has been used for polynomial-time algorithms and for improvement and understanding of the belief propagation. In this work, the holographic transformation is generalized to quantum factor graphs.

Includes members:
  Member "partition functions of normal factor graphs":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "codes on graphs models for elementary algebraic topology and statistical physics")
  Member "normal factor graphs and holographic transformations":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "codes on graphs models for elementary algebraic topology and statistical physics")
  Member "loop calculus and belief propagation for q ary alphabet loop tower":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "gauges loops and polynomials for partition functions of graphical models")
