human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "outer bounds on the admissible source region for broadcast channels with dependent sources"
  Abstract: Outer bounds on the admissible source region for broadcast channels with dependent sources are developed and used to prove capacity results for several classes of sources and channels.

    - "evaluation of marton s inner bound for the general broadcast channel"
    - "a note on outer bounds for broadcast channel"
    - "the capacity region of classes of product broadcast channels"
    - "optimality and approximate optimality of source channel separation in networks"
    - "evaluation of marton s inner bound for the general broadcast channel"
    - "correlated sources over broadcast channels"
