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 "rank metric codes"):
  Abstract: This is a chapter of the upcoming "A Concise Encyclopedia of Coding Theory", W.C. Huffman, J.-L. Kim, and P. Sole' Eds., CRC Press. The chapter gives an introduction to the mathematical theory of rank-metric codes. Treated topics include: definition of rank metric, equivalence of codes, support of a codeword and of a code, duality, weight enumerators and MacWilliams identities, higher rank weights, MRD codes, optimal anticodes, and q-polymatroids associated to a rank-metric code.

Includes members:
  Member "rank metric codes and q polymatroids":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a polymatroid approach to generalized weights of rank metric codes")
  Member "codes endowed with the rank metric":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "tensor representation of rank metric codes")
  Member "on defining generalized rank weights":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a polymatroid approach to generalized weights of rank metric codes")
  Member "relative generalized matrix weights of matrix codes for universal security on wire tap networks":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "reliable and secure multishot network coding using linearized reed solomon codes")
  Member "relative generalized rank weight of linear codes and its applications to network coding":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "reliable and secure multishot network coding using linearized reed solomon codes")
  Member "generalized weights an anticode approach":
