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 "an equivalence between network coding and index coding"):
  Abstract: We show that the network coding and index coding problems are equivalent. This equivalence holds in the general setting which includes linear and non-linear codes. Specifically, we present an efficient reduction that maps a network coding instance to an index coding one while preserving feasibility. Previous connections were restricted to the linear case.

Includes members:
  Member "on the impact of a single edge on the network coding capacity":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a local perspective on the edge removal problem")
  Member "network coding is zero error always possible":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "lossless source coding in the point to point multiple access and random access scenarios")
  Member "lexicographic products and the power of non linear network coding":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "an index coding approach to caching with uncoded cache placement")
  Member "broadcasting with side information":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "privacy utility tradeoff in a guessing framework inspired by index coding")
  Member "non linear index coding outperforming the linear optimum":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "the minrank of random graphs")
  Member "on the relation between the index coding and the network coding problems":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "embedded index coding")
  Member "dualities between entropy functions and network codes":
    also connected through other hyperedges:
      - Hyperedge HE-7 (induced by source paper "a local perspective on the edge removal problem")
