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: "augustin s method part i the renyi center"
  Abstract: A self contained presentation of Renyi's information quantities ---power mean, Renyi information, Renyi divergence, Renyi mean, Renyi capacity, Renyi radius and Renyi center--- is provided. Erven-Harremoes conjecture is proved for any positive order and for any set of probability measures on a given measurable space. A generalization of Erven-Harremoes conjecture is established for the constrained variant of the problem. Finiteness of the order $\alpha$ Renyi capacity is shown to imply the continuity of the Renyi capacity on $(0,\alpha]$ and the uniform equicontinuity of the Renyi information, both as a family of functions of the order indexed by the priors and as a family of functions of the prior indexed by the orders. The Renyi capacities and the Renyi centers of various shift invariant families of probability measures on the unit interval and various families of Poisson processes are derived as examples.

Connected through hyperedge HE-1 (induced by source paper "the augustin center and the sphere packing bound for memoryless channels"):
  with members:
    - "the renyi capacity and center"
    - "augustin s method part ii the sphere packing bound"
    - "the sphere packing bound via augustin s method"
    - "renyi divergence and kullback leibler divergence"
    - "refinement of the sphere packing bound asymmetric channels"
