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: "typicality graphs large deviation analysis"
  Abstract: Let X and Y be finite alphabets and PXY a joint distribution over them, with PX and PY representing the marginals. For any " > 0, the set of n-length sequences x n and y n that are jointly typical [1] according to PXY can be represented on a bipartite graph. We present a formal definition of such a graph, known as a typicality graph, and study some of its properties.

Connected through hyperedge HE-1 (induced by source paper "large deviations behavior of the logarithmic error probability of random codes"):
  with members:
    - "error exponents of typical random trellis codes"
    - "error exponents of typical random codes for the colored gaussian channel"
    - "error exponents of typical random codes"
