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: "an improvement of the feng rao bound for primary codes"
  Abstract: We present a new bound for the minimum distance of a general primary linear code. For affine variety codes defined from generalised C_{ab} curves the new bound often improves dramatically on the Feng-Rao bound for primary codes. The method does not only work for the minimum distance but can be applied to any generalised Hamming weight

Connected through hyperedge HE-1 (induced by source paper "relative generalized hamming weights of one point algebraic geometric codes"):
  with members:
    - "relative generalized rank weight of linear codes and its applications to network coding"
    - "feng rao decoding of primary codes"
    - "further improvements on the feng rao bound for dual codes"
    - "on the order bounds for one point ag codes"
    - "mds codes on the erasure erasure wiretap channel"
    - "strongly secure ramp secret sharing schemes for general access structures"

Connected through hyperedge HE-2 (induced by source paper "quantum codes from affine variety codes and their subfield subcodes"):
  with members:
    - "css like constructions of asymmetric quantum codes"
    - "the dimension of subcode subfields of shortened generalized reed solomon codes"
    - "subfield subcodes of generalized toric codes"
    - "on the structure of generalized toric codes"
